GAY-LUSSAC';S law regardg the posn of gas by volume was ma known about a hundred years ago. The paper which he elaborated , havg been read to the Société philomatique on December 31, 1808, was published the Mémoir la Société d'Arcil the followg year. Sce then the law has e to have a history of s own. Chemists were at a loss and ma many efforts to get and the atomic theory to su one another, and the place of the law science, though not now likely to change, was for long unsettled and dub.

French chemist Joseph Louis Gay-Lsac proposed two fundamental laws of gas the early 19th century. While one is generally attributed to a fellow untryman, the other is well known as Gay-Lsac’s law.
Joseph Louis Gay-Lsac (1778–1850) grew up durg both the French and Chemil Revolutns.

Gay-Lsac’s Law is a Gas Law which Stat that the Prsure of a Gas (of a Given mass, kept at a nstant Volume) Vari Directly wh s Absolute Temperature. * gay lussac's law founder *
Gay-Lsac’s own reer as a profsor of physics and chemistry began at the Éle Polytechnique. 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.
This ncln subsequently beme known as Gay-Lsac’s law. 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. Featured image: Undated portra of Joseph Louis Gay-Lsac.

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. Gay-Lsac was the elst son of a provcial lawyer and royal official who lost his posn wh the French Revolutn of 1789.
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. Gay-Lsac proved to be an exemplary stunt durg his studi there om 1797 to 1800.
The society’s first volume of memoirs, published 1807, clud ntributns om Gay-Lsac. 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 GAS LAW EXAMPL
Gay-Lsac’s first publitn (1802), however, was on the thermal expansn of gas.
Charl as “Charl’s law, ” was the first of several regulari the behavur of matter that Gay-Lsac tablished.
” Of the laws Gay-Lsac disvered, he remas bt known for his law of the bg volum of gas (1808). 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.

As a young man, Gay-Lsac participated dangero explos for scientific purpos. 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. In 1805–06, amid the Napoleonic wars, Gay-Lsac embarked upon a European tour wh another Arcueil lleague, the Pssian explorer Alexanr von Humboldt.
