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. 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. 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.

Gay-Lsac’s appotment to the faculty of the Éle Polytechnique 1804 provid him wh laboratory facili the centre of Paris.
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].
Begng 1816, Gay-Lsac served as the jot edor of the Annal chimie et physique, a posn he shared wh his former Arcueil lleague François Arago.
GAY-LSAC
Joseph-Louis Gay-Lsac (1778-1850) was a French physicist and chemist born December 1778. His ma ntributn to science were two laws on the behavr of gas. * gay lussac contribution *
Still, Gay-Lsac did not pe cricism om lleagu for turng away om the path of “pure” science and toward the path of fancial ga.
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. Gay-Lsac published an entire seri of Instctns on subjects rangg om the timatn of potash (1818) to the nstctn of lightng nductors.
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. ” 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.
Joseph Louis Gay-Lsac (1778–1850) lived through three revolutns France and his life reflected the social transformatns takg place around him. Gay-Lsac may be seen as the first 'profsnal' scientist and ed, throughout the book, Profsor Crosland emphasis that he knew how to e his science to solve practil problems and was able to prof nsirably om this applitn.

GAY-LSAC’S LAW
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 contribution *
Although was his laws on gas that have ed Gay-Lsac to go down history, the scientist also veloped other important vtigatns.

JOSEPH LOUIS GAY-LSAC AND HIS WORK ON GAS
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 lussac contribution *
Intertgly, both scientists also disvered de at the same time, but the private sphere, Gay-Lsac married Geneviève Rojot 1811, wh whom he had five disveriGay-Lsac ntued to make new disveri durg the followg years. Gay-Lsac was one of those who bed scientific rearch wh polil rearcher was elected puty 1831 for Hte-Vienne, sce he revalidated 1834 and 1837. The scientist lived there until, the sprg of 1850, he realized that his ath was that time he asked his son to burn a treatise that he had begun to wre and which was entled May 9 of that same year, Louis Joseph Gay-Lsac died the French pal.
Contributns to scienceThe most important ntributns to science ma by Gay-Lsac were related to his studi on the characteristics of addn to the laws that bear his name, Gay-Lsac also stood out for tablishg improvements applible to the chemil dtry.

Charl and Gay-Lsac's LawThe so-lled Charl and Gay-Lsac Law relat the volume and temperature of an ial gas quanty that is kept at a nstant prsure.
Although was Jacqu Charl who disvered this qualy of gas 1787, was Gay-Lsac who published the law for the first time, 's LawGay-Lsac's work that had the most impact led to the law that bears his name. BoronAlthough boron and s pounds have been known and ed sce ancient tim, was not until the 19th century that uld be obtaed wh a high gree of, 1808, Gay-Lsac managed to obta boron wh a 50% pury.

GAY-LSAC'S GAS LAW EXAMPL
The exprs mass relatnships of elements chemil pounds and have been part of the study of chemistry sce before Dalton prented his atomic novelty ntributed by Gay Lsac 1809 was to relate the volum of the products and reactants a chemil reactn wh the proportns of the elements different law of bg volum stat that as gas react wh each other to create other gas, all volum are measured at the same prsure and an example, the French scientist poted out that a volume of oxygen and two of hydrogen that react wh each other give rise to two volum of gaseo water.
Likewise, he llaborated studi on how to make stear ndl and lightng the other hand, Gay-Lsac helped improve the system to obta sulfuric acid and stearic acid. Joseph Louis Gay-Lsac (December 6, 1778 – May 9, 1850) was a French chemist and physicist whose disvery of the law of bg volum of gas chemil reactns paved the way for our unrstandg of molecul and atoms.
In 1789, at the begng of the French Revolutn, his parents found necsary to keep Gay-Lsac at home, where he received his early tn. Gay-Lsac and fellow scientist Jean-Baptiste Bt were missned by the French ernment, at the stigatn of Berthollet and Laplace, to make an ascent a hot air balloon to take measurements of the earth's magic field and perform other experiments.

In orr to take readgs at even greater heights, Gay-Lsac ma another ascent, this time alone, and was able to achieve an elevatn of seven thoand meters, a rerd for that time. Durg this ascent, Gay-Lsac was able to brg back sampl of air, and found their posn to be the same as the air at the earth's surface.
JOSEPH LOUIS GAY-LSAC (1778–1850) AND ANALYTIL CHEMISTRY
In 1805, Gay-Lsac acpanied Alexanr von Humboldt on a year-long tour of Europe, durg which he met many of the famo scientists of his day, cludg Alsandro Volta. In 1807, a year after Gay-Lsac's return to France, Berthollet tablished a society of scientists lled the Societe d'Aucuiel. Among the memoir published by the society clud Gay-Lsac's magic measurements ma durg his European tour, as well as work that he is perhaps bt remembered for, which he formulated what is today generally referred to Gay-Lsac's law of bg volum.
