Joseph Louis Gay-Lsac, a French chemist, was born Dec. 6, 1778. Gay-Lsac is well known to morn chemists for two laws, one relatg the volume of a gas to s temperature (volume creas learly wh temperature), and the send, lled the law of bg...

Gay-Lsac's Law stat that, a closed system of fixed volume, as the temperature of a gas creas, the prsure creas as well and this n be explaed g ketic molecular theory, or how the movement of dividual gas particl affects the behavr of a gas as a whole. Gay-Lsac's Law stat that, a closed system of fixed volume, as the temperature of a gas creas, the prsure creas as well. This n be explaed g ketic molecular theory, or how the movement of dividual gas particl affects the behavr of a gas as a whole. Temperature is a measure of the average ketic energy of a substance, or, how much motn atoms/particl have as a rult of heat energy. As the temperature of a substance ris, s molecul are movg faster or more energetilly. In a gas, when particl are a nfed space, faster movement of gas molecul will crease the number of llisns that molecul have wh each other or wh the ntaer. Thk of tryg to move through a crowd room at a party: if you walk through slowly, you n avoid bumpg to somebody, but if you try to n om one si of the room to the other, chanc are you will lli wh a few people along the way. When gas molecul lli wh their ntaer, we n measure the force per un area of the llisns. We refer to this measurement as the prsure of the gas. When llisns crease, the overall prsure creas. This means that as temperature ris, gas particl move more quickly, which turn them to have more llisns wh their ntaer. We register this crease llisns as prsure. Th, we observe an creased prsure wh an creased temperature, thereby nfirmg Gay-Lsac's Law. * gay lussac theory *
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. 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.

atom - Atom - Dalton, Bohr, Rutherford: English chemist and physicist John Dalton extend Prot’s work and nverted the atomic philosophy of the Greeks to a scientific theory between 1803 and 1808. His book A New System of Chemil Philosophy (Part I, 1808; Part II, 1810) was the first applitn of atomic theory to chemistry. It provid a physil picture of how elements be to form pounds and a phenomenologil reason for believg that atoms exist. His work, together wh that of Joseph-Louis Gay-Lsac of France and Ameo Avogadro of Italy, provid the experimental foundatn of atomic chemistry. On the basis of the law of fe proportns, * gay lussac theory *
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.
SCIENTIST OF THE DAY - JOSEPH LOUIS GAY-LSAC
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.
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.
EXPERIMENT: GAY-LSAC’S LAW
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.

Charl as “Charl’s law,” was the first of several regulari the behavur of matter that Gay-Lsac tablished. He later wrote, “If one were not animated wh the sire to disver laws, they would often pe the most enlightened attentn.” 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. 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. 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.
