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.

GAY-LSAC’S LAW: P AND T

This law was formulated by the French chemist Joseph Gay-Lsac the year 1808.

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. The law of Gay-Lsac is a variant of the ial gas law where the volume of gas is held nstant.

Député Limog (1831-39), profsr chimie générale Méum d’histoire naturelle (1832) et pair France (1839), il cse d’enseigner (1840), mais ntue s recherch et publitns; il t nommé (1840) admistratr la Compagnie s glac Sat-Goba et crée la "tour Gay-Lsac" dans l'e Chny. Gay-Lsac appartient tout entier à l'Éle Polytechnique par son orige, par son ractère, par son enseignement.

GAY LSAC’S LAW OF BG VOLUM OF GAS

Entré à l'Ele Polytechnique en 1797, Gay-Lsac en sort dans le rps s Ponts et Chssé. On ne pte pas mos cent onze publitns où Gay-Lsac a fourni succsivement s donné nouvell à la Science. L'égale dilatatn s gaz et s vaprs a été affirmée par Gay-Lsac, dès 1802, à l'âge 24 ans: c't le premier travail scientifique du « coyen Gay-Lsac, élève Ingénir s Ponts et Chssé » (Annal Chimie et Physique, t.

Mais jourd'hui no pouvons envisager c qutns d'un pot vue pl élevé; l'énoncé Gay-Lsac rte me une gran loi naturelle, malgré l perturbatns xquell elle t soumise; l physiciens, l mathématiciens la nsidèrent me le ractère s gaz parfas. Une tre loi non mos célèbre, qui porte enre jourd'hui le nom Gay-Lsac, t la loi sur l rapports s volum dans l baisons entre l gaz. Ce n't que trois ans après que Gay-Lsac, à la sue nouvell recherch, étend cette observatn à to l gaz.

On pt remarquer que, dans l'tervalle, Dalton ava publié le premier volume son Nouve Système philosophie chimique où il exposa la loi s proportns multipl en l'terprétant par l'hypothèse s atom; on t étonné voir que Dalton, dans son send volume, repose avec une sorte déda la loi Gay-Lsac. Gay-Lsac ava tout sue pris l'importance sa déuverte, r il d début son Mémoire, me pour rattacher cette loi à celle l'égale dilatatn s gaz: « L'attractn s molécul dans l solis et l liquis t la e qui modifie lrs propriétés particulièr et il para que ce n't que quand elle t entièrement déte, me dans l gaz, que l rps, se trouvant placés dans s cirnstanc semblabl, présentent s lois simpl et régulièr.....

La valr cette déuverte paraîtra enre pl gran si l'on réfléch qu' moment où elle fut fae, on discuta enre la qutn savoir si l baisons chimiqu se font en proportns fix ou en tout sort proportns: Berthollet, le maître Gay-Lsac, soutena ntre Prot et Dalton cette doctre erronée, tout en la tempérant par divers rtrictns.

Pour poursuivre l nséquenc la nouvelle loi, Gay-Lsac donna une métho, venue classique, pour détermer l nsés s vaprs: il lcula la nsé vapr théorique du rbone; il lcula ssi à l'avance celle l', p après la déuverte ce rps simple, et un p pl tard l'expérience vérifia le nombre asi obtenu.
