Parallel Computer Architecture Essay Example for Free

Parallel Computer Architecture Essay â€Å"Parallel computing† is a science of calculation t countless computational directives are being â€Å"carried out† at the same time, working on the theory that big problems can time and again be split â€Å"into smaller ones†, that are subsequently resolved â€Å"in parallel†. We come across more than a few diverse type of â€Å"parallel computing: bit-level parallelism, instruction-level parallelism, data parallelism, and task parallelism†. (Almasi, G. S. and A. Gottlieb, 1989) Parallel Computing has been employed for several years, for the most part in high-performance calculation, but awareness about the same has developed in modern times owing to the fact that substantial restriction averts rate of recurrence scale. Parallel computing has turned out to be the leading prototype in â€Å"computer architecture, mostly in the form of multicore processors†. On the other hand, in modern times, power utilization by parallel computers has turned into an alarm. Parallel computers can be generally categorized in proportion â€Å"to the level at which the hardware† sustains parallelism; â€Å"with multi-core and multi-processor workstations† encompassing several â€Å"processing† essentials inside a solitary mechanism at the same time â€Å"as clusters, MPPs, and grids† employ several workstations â€Å"to work on† the similar assignment. (Hennessy, John L. , 2002) Parallel computer instructions are very complicated to inscribe than chronological ones, for the reason that from synchronization commence more than a few new modules of prospective software virus, of which race situations are mainly frequent. Contact and association amid the dissimilar associate assignments is characteristically one of the supreme obstructions to receiving superior analogous program routine. The acceleration of a program due to parallelization is specified by Amdahls law which will be later on explained in detail. Background of parallel computer architecture Conventionally, computer software has been inscribed for sequential calculation. In order to find the resolution to a â€Å"problem†, â€Å"an algorithm† is created and executed â€Å"as a sequential stream† of commands. These commands are performed on a CPU on one PC. No more than one command may be implemented at one time, after which the command is completed, the subsequent command is implemented. (Barney Blaise, 2007) Parallel computing, conversely, utilizes several processing fundamentals at the same time to find a solution to such problems. This is proficiently achieved by splitting â€Å"the problem into† autonomous divisions with the intention that every â€Å"processing† factor is capable of carrying out its fraction â€Å"of the algorithm† concurrently by means of the other processing factor. The processing† fundamentals can be varied and comprise properties for example a solitary workstation with several processors, numerous complex workstations, dedicated hardware, or any amalgamation of the above. (Barney Blaise, 2007) Incidence balancing was the leading cause for enhancement in computer routine starting sometime in the mid-1980s and continuing till â€Å"2004†. â€Å"The runtime† of a series of instructions is equivalent to the amount of commands reproduced through standard instance for each command. Retaining the whole thing invariable, escalating the clock occurrence reduces the standard time it acquires to carry out a command. An enhancement in occurrence as a consequence reduces runtime intended for all calculation bordered program. (David A. Patterson, 2002) â€Å"Moores Law† is the pragmatic examination that â€Å"transistor† compactness within a microchip is changed twofold approximately every 2 years. In spite of power utilization issues, and frequent calculations of its conclusion, Moores law is still effective to all intents and purposes. With the conclusion of rate of recurrence leveling, these supplementary transistors that are no more utilized for occurrence leveling can be employed to include additional hardware for parallel division. (Moore, Gordon E, 1965) Amdahl’s Law and Gustafson’s Law: Hypothetically, the expedition from parallelization should be linear, repeating the amount of dispensation essentials should divide the â€Å"runtime†, and repeating it subsequent â€Å"time and again† dividing â€Å"the runtime†. On the other hand, very a small number of analogous algorithms attain most favorable acceleration. A good number â€Å"of them have a near-linear† acceleration for little figures of â€Å"processing† essentials that levels out into a steady rate for big statistics of â€Å"processing† essentials. The possible acceleration of an â€Å"algorithm on a parallel† calculation stage is described by â€Å"Amdahls law†, initially devised by â€Å"Gene Amdahl† sometime â€Å"in the 1960s†. (Amdahl G. , 1967) It affirms that a little segment of the â€Å"program† that cannot be analogous will bound the general acceleration obtainable from â€Å"parallelization†. Whichever big arithmetical or manufacturing problem is present, it will characteristically be composed of more than a few â€Å"parallelizable† divisions and quite a lot of â€Å"non-parallelizable† or â€Å"sequential† divisions. This association is specified by the â€Å"equation S=1/ (1-P) where S† is the acceleration of the â€Å"program† as an aspect of its unique chronological â€Å"runtime†, and â€Å"P† is the division which is â€Å"parallelizable†. If the chronological segment of â€Å"a program is 10% â€Å"of the start up duration, one is able to acquire merely a 10 times acceleration, in spite of of how many computers are appended. This sets a higher bound on the expediency of adding up further parallel implementation components. â€Å"Gustafsons law† is a different â€Å"law in computer† education, narrowly connected to â€Å"Amdahls law†. It can be devised as â€Å"S(P) = P ? (P-1) where P† is the quantity of â€Å"processors†, S is the acceleration, and ? the â€Å"non-parallelizable† fraction of the procedure. â€Å"Amdahls law† supposes a permanent â€Å"problem† volume and that the volume of the chronological division is autonomous of the quantity of â€Å"processors†, while â€Å"Gustafsons law† does not construct these suppositions. Applications of Parallel Computing Applications are time and again categorized in relation to how frequently their associative responsibilities require coordination or correspondence with every one. An application demonstrates superior grained parallelism if its associative responsibilities ought to correspond several times for each instant; it shows commonly grained parallelism if they do not correspond at several instances for each instant, and it is inadequately equivalent if they hardly ever or by no means have to correspond. Inadequately parallel claims are measured to be uncomplicated to parallelize. Parallel encoding languages and parallel processor have to have a uniformity representation that can be more commonly described as a â€Å"memory model†. The uniformity â€Å"model† describes regulations for how procedures on processor â€Å"memory† take place and how consequences are formed. One of the primary uniformity â€Å"models† was a chronological uniformity model made by Leslie Lamport. Chronological uniformity is the condition of â€Å"a parallel program that it’s parallel† implementation generates the similar consequences as a â€Å"sequential† set of instructions. Particularly, a series of instructions is sequentially reliable as Leslie Lamport states that if the consequence of any implementation is equal as if the procedures of all the â€Å"processors† were carried out in some â€Å"sequential† array, and the procedure of every entity workstation emerges in this series in the array detailed by its series of instructions. Leslie Lamport, 1979) Software contractual memory is a familiar form of constancy representation. Software contractual memory has access to database hypothesis the notion of infinitesimal connections and relates them to â€Å"memory† contact. Scientifically, these â€Å"models† can be symbolized in more than a few approaches. Petri nets, which were established in the physician hypothesis of Carl Adam Petri some time in 1960, happen to be a premature effort to cipher the set of laws of uniformity models. Dataflow hypothesis later on assembled upon these and Dataflow structural designs were formed to actually put into practice the thoughts of dataflow hypothesis. Commencing â€Å"in the late 1970s†, procedure of â€Å"calculi† for example â€Å"calculus of† corresponding structures and corresponding â€Å"sequential† procedures were build up to authorize arithmetical interpretation on the subject of classification created of interrelated mechanisms. More current accompaniments to the procedure â€Å"calculus family†, for example the â€Å"? calculus†, have additionally the ability for explanation in relation to dynamic topologies. Judgments for instance Lamports TLA+, and arithmetical representations for example sketches and Actor resultant drawings, have in addition been build up to explain the performance of simultaneous systems. (Leslie Lamport, 1979) One of the most important classifications of recent times is that in which Michael J. Flynn produced one of the most basic categorization arrangements for parallel and sequential processors and set of instructions, at the present recognized as â€Å"Flynns taxonomy†. Flynn† categorized â€Å"programs† and processors by means of propositions if they were working by means of a solitary set or several â€Å"sets of instructions†, if or not those commands were utilizing â€Å"a single or multiple sets† of information. â€Å"The single-instruction-single-data (SISD)† categorization is corresponding to a completely sequential process. â€Å"The single-instruction-multiple-data (SIMD)† categorization is similar to doing the analogous procedure time after time over a big â€Å"data set†. This is usually completed in â€Å"signal† dispensation application. Multiple-instruction-single-data (MISD)† is a hardly ever employed categorization. While computer structural designs to manage this were formulated for example systolic arrays, a small number of applications that relate to this set appear. â€Å"Multiple-instruction-multiple-data (MIMD)† set of instructions are without a doubt the for the most part frequent sort of parallel procedures. (Hennessy, John L. , 2002) Types of Parallelism There are essentially in all 4 types of â€Å"Parallelism: Bit-level Parallelism, Instruction level Parallelism, Data Parallelism and Task Parallelism. Bit-Level Parallelism†: As long as 1970s till 1986 there has been the arrival of very-large-scale integration (VLSI) microchip manufacturing technology, and because of which acceleration in computer structural design was determined by replication of â€Å"computer word† range; the â€Å"amount of information† the computer can carry out for each sequence. (Culler, David E, 1999) Enhancing the word range decreases the quantity of commands the computer must carry out to execute an action on â€Å"variables† whose ranges are superior to the span of the â€Å"word†. or instance, where an â€Å"8-bit† CPU must append two â€Å"16-bit† figures, the central processing unit must initially include the â€Å"8 lower-order† fragments from every numeral by means of the customary calculation order, then append the â€Å"8 higher-order† fragments employing an â€Å"add-with-carry† command and the carry fragment from the lesser arr ay calculation; therefore, an â€Å"8-bit† central processing unit necessitates two commands to implement a solitary process, where a â€Å"16-bit† processor possibly will take only a solitary command unlike â€Å"8-bit† processor to implement the process. In times gone by, â€Å"4-bit† microchips were substituted with â€Å"8-bit†, after that â€Å"16-bit†, and subsequently â€Å"32-bit† microchips. This tendency usually approaches a conclusion with the initiation of â€Å"32-bit† central processing units, which has been a typical in wide-ranging principles of calculation for the past 20 years. Not until in recent times that with the arrival of â€Å"x86-64† structural designs, have â€Å"64-bit† central processing unit developed into ordinary. (Culler, David E, 1999) In â€Å"Instruction level parallelism a computer program† is, basically a flow of commands carried out by a central processing unit. These commands can be rearranged and coalesced into clusters which are then implemented in â€Å"parallel† devoid of altering the effect of the â€Å"program†. This is recognized as â€Å"instruction-level parallelism†. Progress in â€Å"instruction-level parallelism† subjugated â€Å"computer† structural design as of the median of 1980s until the median of 1990s. Contemporary processors have manifold phase instruction channels. Each phase in the channel matches up to a dissimilar exploit the central processing unit executes on that channel in that phase; a central processing unit with an â€Å"N-stage† channel can have equal â€Å"to N† diverse commands at dissimilar phases of conclusion. The â€Å"canonical† illustration of a channeled central processing unit is a RISC central processing unit, with five phases: Obtaining the instruction, deciphering it, implementing it, memory accessing, and writing back. In the same context, the Pentium 4 central processing unit had a phase channel. Culler, David E, 1999) Additionally to instruction-level parallelism as of pipelining, a number of central processing units can copy in excess of one command at an instance. These are acknowledged as superscalar central processing units. Commands can be clustered jointly simply â€Å"if there is no data† reliance amid them. â€Å"Scoreboarding† and the â€Å"Tomasulo algorithm† are two of the main frequent modus operandi for putting into practice inoperative implementation and â€Å"instruction-level parallelism†. Data parallelism† is â€Å"parallelism† intrinsic in â€Å"program† spheres, which center on allocating the â€Å"data† transversely to dissimilar â€Å"computing† nodules to be routed in parallel. Parallelizing loops often leads to similar (not necessarily identical) operation sequences or functions being performed on elements of a large data structure. (Culler, David E, 1999) A lot of technical and manufacturing applications display data â€Å"parallelism†. â€Å"Task parallelism† is the feature of a â€Å"parallel† agenda that completely dissimilar computation can be carried out on both the similar or dissimilar â€Å"sets† of information. This distinguishes by way of â€Å"data parallelism†; where the similar computation is carried out on the identical or unlike sets of information. â€Å"Task parallelism† does more often than not balance with the dimension of a quandary. (Culler, David E, 1999) Synchronization and Parallel slowdown: Associative chores in a parallel plan are over and over again identified as threads. A number of parallel computer structural designs utilize slighter, insubstantial editions of threads recognized as fibers, at the same time as others utilize larger editions acknowledged as processes. On the other hand, threads is by and large acknowledged as a nonspecific expression for associative jobs. Threads will frequently require updating various variable qualities that is common among them. The commands involving the two plans may be interspersed in any arrangement. A lot of parallel programs necessitate that their associative jobs proceed in harmony. This entails the employment of an obstruction. Obstructions are characteristically put into practice by means of a â€Å"software lock†. One category of â€Å"algorithms†, recognized as â€Å"lock-free and wait-free algorithms†, on the whole keeps away from the utilization of bolts and obstructions. On the other hand, this advancement is usually easier said than done as to the implementation it calls for properly intended data organization. Not all parallelization consequences in acceleration. By and large, as a job is divided into increasing threads, those threads expend a growing segment of their instant corresponding with each one. Sooner or later, the transparency from statement controls the time exhausted resolving the problem, and supplementary parallelization which is in reality, dividing the job weight in excess of still more threads that amplify more willingly than reducing the quantity of time compulsory to come to an end. This is acknowledged as parallel deceleration. Central â€Å"memory in a parallel computer† is also â€Å"shared memory† that is common among all â€Å"processing† essentials in a solitary â€Å"address space†, or â€Å"distributed memory† that is wherein all processing components have their individual confined address space. Distributed memories consult the actuality that the memory is rationally dispersed, however time and again entail that it is bodily dispersed also. â€Å"Distributed shared memory† is an amalgamation of the two hypotheses, where the â€Å"processing† component has its individual confined â€Å"memory† and right of entry to the â€Å"memory† on non-confined â€Å"processors†. Admittance to confined â€Å"memory† is characteristically quicker than admittance to non-confined â€Å"memory†. Conclusion: A mammoth change is in progress that has an effect on all divisions of the parallel computing architecture. The present traditional course in the direction of multicore will eventually come to a standstill, and finally lasting, the trade will shift quickly on the way to a lot of interior drawing end enclosing hundreds or thousands of cores for each fragment. The fundamental incentive for assuming parallel computing is motivated by power restrictions for prospective system plans. The alteration in structural design are also determined by the association of market dimensions and assets that go with new CPU plans, from the desktop PC business in the direction of the customer electronics function.

Bartleby, The Failure :: essays research papers

Bartleby, the Failure It is not rare, sometimes it is even common, that an author speaks about his or her self in their works. Herman Melville's "Bartleby, the Scrivener" is often considered such a story. Many of the characters in the story and images created allude to Melville's writing career, which was generally deemed a failure. The main character in the story can either be Bartleby or the narrator, but Melville partially embodies both of them. We are understanding towards the narrator's reasoning for keeping Bartleby and for the sympathy he shows for Bartleby. After the general failure of Moby Dick, at least in Melville's time, he immediately wrote Pierre, which was a deeply personal novel. This self pity could have been continued in "Bartleby, the Scrivener". In addition, Bartleby seemed to feel that continuing copying was worthless, possibly from spending many years in a dead letter office. Melville probably felt this way, but needed to continue writing to support his family. When Bartleby is in prison, he wastes away without abruptly dying, a degeneration until the point no one notices his absence. Melville had reached the prime of his popularity early in his career, so when he published Moby Dick, his career was already in decline. His disappointment was only to increase as his career diminished until his death which was hardly noticed in the literary community. The narrator also resembles Melville, but in a different way. Melville uses the narrator to view his own situation from a 3rd person perspective. He attempts, and is somewhat successful, in getting readers to feel sympathy for Bartleby, therefore, sympathy for him. On the contrary, the narrator also scorns Bartleby's persistence after he stops copying: "In plain fact, he had now become a millstone to me†¦"(1149). In this respect, the narrator also represents Melville's literary critics. Behind the relationship between Melville, the narrator, and Bartleby, one can also see the relationship between the narrator and an ideal audience that Melville would have wanted. He probably wished that his writing would be more popular among the readers, although he professed his own demise with Bartleby's atrophy. His other employees, Turkey, Nippers, and Ginger Nut, were similar to other writers who inspired Melville, such as

The Human Development Index Health And Social Care Essay

Human Development Index ( HDI ) ranking of eight major economic systems of South Asia in the 2009 Human Development Report, released earlier this hebdomad, show a blue record with all states relegated to the 3rd class of medium development provinces with the planetary rankings falling in the 2nd half of the listings of 182 states. Exceeding the superior list of the South Asiatic states in 2007, the day of the month for which comprehensive information was available, was Maldives ( 95 ) , followed by Sri Lanka ( 102 ) , Bhutan ( 132 ) , India ( 134 ) , Pakistan ( 141 ) , Nepal ( 144 ) , Bangladesh ( 146 ) and Afghanistan ( 182 ) . The worst facet of the India ‘s low HDI ranking was its blue record in even a nucleus country like life anticipation. Life anticipation at birth in India was merely 63.4 old ages, which pushed it down in the last but one class, merely above Afghanistan where the life anticipation was a blue 43.6 old ages. South Asiatic states hiting above India in life anticipation included Bhutan and Bangladesh ( 65.7 old ages each ) , Pakistan ( 66.2 old ages ) , Nepal ( 66.3 old ages ) , Maldives ( 71.1 old ages ) and even the civil war hit Sri Lanka ( 74 old ages ) . India ‘s record on life anticipation is made worse by the low rates of endurance of immature individuals. The estimations show that the chance of deceasing before the age of 40 is among the highest in India, with 15.5 % of the cohort fring their lives. This is about three times the degree of mortality in Sri Lanka where merely 5.5 % of the population fail to traverse the 40-age grade. Afghanistan fared the worst where the opportunities of endurance over 40 was worst-with about 40 % of the individuals deceasing before achieving this age. What makes affairs even worse is that the chances of bettering opportunities of endurance of the younger age groups and bettering overall life anticipation may go on to be hampered by its dreamy attack to bettering kid public assistance, particularly the nutritionary degrees. A comparing of the statistics on scraggy kids in South Asia show that India ‘s record was among the worst, with 46 % of the kids scraggy, a record which was merely following to that of Bangladesh where the portion of†¦ The HDI combines three dimensions: Life anticipation at birth, as an index of population wellness and length of service Knowledge and instruction, as measured by the grownup literacy rate ( with two-thirds burdening ) and the combined primary, secondary, and third gross registration ratio ( with one-third weighting ) . Standard of life, as indicated by the natural logarithm of gross domestic merchandise per capita at buying power para.[ edit ] MethodologyThe Physical Quality of Life Index ( PQLI ) is an effort to mensurate the quality of life or wellbeing of a state. The value is the norm of three statistics: basic literacy rate, infant mortality, and life anticipation at age one, all every bit weighted on a 0 to 100 graduated table. It was developed for the Overseas Development Council in the mid-1970s by Morris David Morris, as one of a figure of steps created due to dissatisfaction with the usage of GNP as an index of development. PQLI might be regarded as an betterment but portions the general jobs of mensurating quality of life in a quantitative manner. It has besides been criticized because there is considerable convergence between infant mortality and life anticipation. The UN Human Development Index is a more widely used agencies of mensurating wellbeing. Stairss to Calculate Physical Quality of Life: 1 ) Find per centum of the population that is literate ( literacy rate ) . 2 ) Find the infant mortality rate. ( out of 1000 births ) INDEXED Infant Mortality Rate = ( 166 – infant mortality ) A- 0.625 3 ) Find the Life Expectancy. INDEXED Life Expectancy = ( Life expectancy – 42 ) A- 2.7 4 ) Physical Quality of Life = ( Literacy Rate + INDEXED Infant Mortality Rate + INDEXED Life Expectancy )_________________________________________________________________________3 The term quality of life is used to measure the general wellbeing of persons and societies. The term is used in a broad scope of contexts, including the Fieldss of international development, health care, and political relations. Quality of life should non be confused with the construct of criterion of life, which is based chiefly on income. Alternatively, standard indexs of the quality of life include non merely wealth and employment, but besides the built environment, physical and mental wellness, instruction, diversion and leisure clip, and societal belonging. [ 1 ] Harmonizing to ecological economic expert Robert Costanza: While Quality of Life ( QOL ) has long been an explicit or inexplicit policy end, equal definition and measuring have been elusive. Diverse â€Å" nonsubjective † and â€Å" subjective † indexs across a scope of subjects and graduated tables, and recent work on subjective wellbeing ( SWB ) studies and the psychological science of felicity have spurred renewed involvement. [ 2 ] Besides often related are constructs such as freedom, human rights, and felicity. However, since felicity is subjective and difficult to mensurate, other steps are by and large given precedence. It has besides been shown that felicity, every bit much as it can be measured, does non needfully increase correspondingly with the comfort that consequences from increasing income. As a consequence, criterion of life should non be taken to be a step of felicity. [ 1 ] [ 3 ] The Child Development Index ( CDI ) is an index uniting public presentation steps specific to kids – instruction, wellness and nutrition – to bring forth a mark on a graduated table of 0 to 100. A nothing mark would be the best. The higher the mark, the worse kids are doing. The Child Development Index was developed by Save the Children UK in 2008 through the parts of Terry McKinley, Director of the Centre for Development Policy and Research at the School of Oriental and African Studies ( SOAS ) , University of London, with support from Katerina Kyrili. The indexs which make up the index were chosen because they are easy available, normally understood, and clearly declarative of kid well-being. The three indexs are: Health: the under-five mortality rate ( the chance of deceasing between birth and five old ages of age, expressed as a per centum on a graduated table of 0 to 340 deceases per 1,000 unrecorded births ) . This means that a zero mark in this constituent equals an underfive mortality rate of 0 deceases per 1,000 unrecorded births, and a mark of 100 peers our upper edge of 340 deceases per 1,000 unrecorded births. The upper edge is higher than any state has of all time reached ; Niger came the closest in the ninetiess with 320 under-five deceases per 1,000 unrecorded births. Nutrition: the per centum of under fives who are reasonably or badly scraggy. The common definition of reasonably or badly scraggy, which we use here, is being below two standard divergences of the average weight for age of the mention population. Education: the per centum of primary school-age kids who are non enrolled in school. For our step of instruction want, we use the antonym of the Net Primary Enrolment rate -ie, 100 – the NER. This gives us the per centum of primary school-age kids who are non enrolled. What does the Child Development Index state us about how kids are doing around the universe? Are some states doing good advancement in bettering child wellbeing? Is it acquiring worse in other states? The Child Development Index replies these inquiries. The index measures child wellbeing over three periods from 1990. Japan is in first topographic point, hiting merely 0.4. Niger in Africa is in 137th topographic point, with the highest mark, 58, in 2000-2006. Overall, child wellbeing as improved by 34 % since 1990, but advancement isNewHuman Development Index: The HDI combines normalized steps of life anticipation, literacy, educational attainment, and GDP per capita for states worldwide. It is claimed as a standard agency of mensurating human development-a construct that, harmonizing to the United Nations Development Program ( UNDP ) , refers to the procedure of widening the options of individuals, giving them greater chances for instruction, wellness attention, income, employment, etc. The basic usage of HDI is to mensurate a state ‘s development. The HDI combines three basic dimensions: Life anticipation at birth, as an index of population wellness and length of service. Knowledge and instruction, as measured by the grownup literacy rate ( with two-thirds burdening ) and the combined primary, secondary, and third gross registration ratio ( with one-third weighting ) . Standard of life, as measured by the natural logarithm of gross domestic merchandise per capita. The Human Development Index ( HDI ) so represents the norm of the undermentioned three general indices: Life Expectancy Index ( LEI ) = ( ( LE – 25 ) / ( 85-25 ) ) Education Index ( EI ) = ( 0.667 x ALI ) + ( .334 x GEI ) ALI is Adult Literacy Rate, GEI is Gross Enrolment Index. GDP = [ log ( GDP personal computer ) -log ( 100 ) ] / [ log ( 40000 ) -log ( 100 ) ] HDI measures measure and quality and includes life anticipation, literacy, and existent GDP/capita. Objectivity is a major job with any index. HDI is no exclusion. Assignment of weights is an illustration of flightiness without justification and the HDI index is sensitive to the weights assigned. A more serious unfavorable judgment of the HDI is the weighting of each rank order of the state by 1/3 ( LEI, EI, GDP ) and summing the leaden ranking of the three indexs.OtherLAJWANTI ASWANI.53, Mukta Madhu Society, Bhairvnath, Maninagar, Ahmedabad – 08 Mobile: +91 9974100326 Electronic mail: lajwanti9 @ gmail.comCareer Objective:To run into the organisational aim, attain highs in the occupation profile provided through my accomplishments and competency in Human Resources Management and General Administration.Core CompetencesRecruitment, Head Hunting, Change Management, Performance Appraisal, Attrition Analysis, Leave Policy Formulation.

Difference Between Physical and Chemical Properties

Measurable characteristics of matter may be categorized as either chemical or physical properties. What is the difference between a chemical property and a physical property? The answer has to do with  chemical and physical changes  of matter. A Physical Property A  physical property  is an aspect of matter that can be observed or measured without changing its chemical composition.  Examples of physical properties  include color, molecular weight, and volume. A Chemical Property A  chemical property  may only be observed  by changing the chemical  identity of a substance. In other words, the only way to observe a chemical property is by performing a chemical reaction. This property measures the potential for undergoing a  chemical change.  Examples of chemical properties  include reactivity, flammability and oxidation states. Telling Physical and Chemical Properties Apart Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change. Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different. Look for Tell-Tale Signs of a Chemical Change Usually, you dont have the chemical reaction for a process. You can look for tell-tale signs of a chemical change. These include bubbling, color change, temperature change, and precipitation formation. If you see signs of a chemical reaction, the characteristic you are measuring is most likely a chemical property. If these signs are absent, the characteristic is probably a physical property.
