GAY LSAC’S LAW

Gay-Lsac’s law is a gas law which stat that the prsure exerted by a gas (of a given mass and kept at a nstant volume) vari directly wh the absolute temperature of the gas.

JOSEPH-LOUIS GAY-LSAC

Gay-Lsac’s law impli that the rat of the ial prsure and temperature is equal to the rat of the fal prsure and temperature for a gas of a fixed mass kept at a nstant volume.

When a prsurized aerosol n (such as a odorant n or a spray-pat n) is heated, the rultg crease the prsure exerted by the gas on the ntaer (owg to Gay-Lsac’s law) n rult an explosn.

In an attempt to measure the magic field of the earth at high elevatn, Gay-Lsac held the world rerd for the hight balloon flight for about fifty years. Joseph-Louis Gay-Lsac, (born December 6, 1778, Sat-Léonard--Noblat, France—died May 9, 1850, Paris), French chemist and physicist who pneered vtigatns to the behavur of gas, tablished new techniqu for analysis, and ma notable advanc applied chemistry.

Early his schoolg, Gay-Lsac acquired an tert science, and his mathematil abily enabled him to pass the entrance examatn for the newly found Éle Polytechnique, where stunts’ expens were paid by the state. At Arcueil, Berthollet was joed by the ement mathematician Pierre-Simon Laplace, who engaged Gay-Lsac experiments on pillary orr to study short-range forc. Gay-Lsac’s approach to the study of matter was nsistently volumetric rather than gravimetric, ntrast to that of his English ntemporary John Dalton.

Another example of Gay-Lsac’s fondns for volumetric rats appeared an 1810 vtigatn to the posn of vegetable substanc performed wh his iend Louis-Jacqu Thenard.

In a followg solo flight, Gay-Lsac reached 7, 016 metr (more than 23, 000 feet), thereby settg a rerd for the hight balloon flight that remaed unbroken for a half-century.

Gay-Lsac’s rearch together wh the patronage of Berthollet and the Arcueil group helped him to ga membership the prtig First Class of the Natnal Instute (later the Amy of Scienc) at an early stage his reer (1806). Three years prevly Gay-Lsac had been appoted to the junr post of répétr at the Éle Polytechnique where, 1810, he received a profsorship chemistry that clud a substantial salary.

GAY-LSAC'S LAW DEFN

Rivalry between Gay-Lsac and Davy reached a climax over the de experiments Davy rried out durg an extraordary vis to Paris November 1813, at a time when France was at war wh Bra.

Gay-Lsac prented a much more plete study of de a long memoir prented to the Natnal Instute on Augt 1, 1814, and subsequently published the Annal chimie. In 1815 Gay-Lsac experimentally monstrated that pssic acid was simply hydrocyanic acid, a pound of rbon, hydrogen, and nrogen, and he also isolated the pound cyanogen [(CN)2 or C2N2]. Prevly a few c trials had been rried out to timate the strength of chlore solutns bleachg, but Gay-Lsac troduced a scientific rigour to chemil quantifitn and vised important modifitns to apparat.

The prcipl of volumetric analysis uld be tablished only through Gay-Lsac’s theoretil and practil geni but, once tablished, the analysis self uld be rried out by a junr assistant wh brief trag. In 1848 (the year of revolutns) Gay-Lsac rigned om his var appotments Paris, and he retired to a untry hoe the neighbourhood of his youth that was stocked wh his library and a private laboratory.

WHAT IS THE DIFFERENCE BETWEEN GAY LSACS LAW AND AVOGADROS LAW

” In a logy livered after his ath at the Amy of Scienc, his iend, the physicist Arago, summed up Gay-Lsac’s scientific work as that of “an gen physicist and an outstandg chemist. In 1804 Gay-Lsac ma several darg ascents of over 7, 000 meters above sea level hydrogen-filled balloons—a feat not equaled for another 50 years—that allowed him to vtigate other aspects of gas.

In 1808 Gay-Lsac announced what was probably his sgle greatt achievement: om his own and others’ experiments he duced that gas at nstant temperature and prsure be simple numeril proportns by volume, and the rultg product or products—if gas—also bear a simple proportn by volume to the volum of the reactants.

Wh his fellow profsor at the Éle Polytechnique, Louis Jacqu Thénard, Gay-Lsac also participated early electrochemil rearch, vtigatg the elements disvered by s means.

Gay-Lsac’s law is siar to Charl’s law, the only difference beg that the term “volume” Charl’s law is replaced by the term “prsure” Gay-Lsac’s law.

Gay-Lsac’s Law is very siar to Charl’s Law; the only difference is that a Charl’s Law experiment, the ntaer is flexible, whereas, a Gay-Lsac’s Law experiment, the ntaer is rigid.

Hence, Gay-Lsac’s Law impli that for a gas of a fixed mass kept at a nstant volume, the ial prsure and temperature rat is equal to the rat of the fal prsure and temperature. This is bee when a prsurized aerosol n (such as a odorant) is heated, the prsure exerted by the gas on the walls of the ntaer creas(owg to Gay-Lsac’s Law) and n rult an explosn.

Gay-Lsac's law is an ial gas law which stat that at nstant volume, the prsure of an ial gas is directly proportnal to s absolute temperature ( Kelv).

Gay-Lsac is sometim creded as beg the first to state Dalton's law, which says that the total prsure of a gas is the sum of the partial prsur of dividual gas.

This article will discs the differenc between Gay-Lsac’s Law and Avogadro’s Law, as well as provi answers to some equently asked qutns about the two laws. Gay-Lsac’s Law, also known as the Prsure Law, stat that the prsure of a given amount of gas held at a nstant volume is directly proportnal to s absolute temperature.

Another difference between Gay-Lsac’s Law and Avogadro’s Law is that Gay-Lsac’s Law appli only to ial gas, while Avogadro’s Law appli to all gas, cludg non-ial gas. Gay-Lsac’s law stat that the prsure and temperature of an ial gas are directly proportnal, assumg nstant mass and ’s law or Amonton’s law stat that the absolute temperature and prsure of an ial gas are directly proportnal, unr ndns of nstant mass and volume.

GAY-LSAC'S LAW

Gay-Lsac formulated the law 1802, but was a formal statement of the relatnship between temperature and prsure scribed by French physicist Guillme Amonton the late 1600’’s law stat the temperature and prsure of an ial gas are directly proportnal, assumg nstant mass and ’s Law FormulaHere are the three mon formulas for Gay-Lsac’s law:P ∝ T(P1/T1) = (P2/T2)P1T2 = P2T1P stands for prsure, while T is absolute temperature.

Exampl of Gay-Lsac’s Law Everyday LifeHere are exampl of Gay-Lsac’s law everyday life:Tire prsure: Automobile tire prsure drops on a ld day and soars on a hot day. Siarly, halvg the absolute temperature halv the Gay-Lsac’s and Amonton’s LawsGay-Lsac stated that all gas have the same average thermal expansivy at nstant temperature and prsure. The example problems e Gay-Lsac's law to fd the prsure of gas a heated ntaer as well as the temperature you would need to change the prsure of gas a ntaer.
