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. 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.

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. 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.

” 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.

1804 – He and Jean-Baptiste Bt ma a hydrogen-balloon ascent; a send ascent the same year by Gay-Lsac alone attaed a height of 7, 016 metr (23, 018 ft) an early vtigatn of the Earth's atmosphere.

Gay-Lsac narrowly avoid nscriptn and by the time of entry to the Éle Polytechnique his father had been arrted (due to Robpierre's Reign of Terror).

1802 – Gay-Lsac first formulated the law, Gay-Lsac's Law, statg that if the mass and volume of a gas are held nstant then gas prsure creas learly as the temperature ris. Joseph Louis Gay-Lsac was a French scientist who studied both physics and chemistry; he is bt known for disverg that water was ma up of two parts hydrogen and one part oxygen.

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.

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. ChloreAs wh the boron rearch, Gay-Lsac and Humphry Davy aga agreed when me to prentg a fdg on this ocsn, both scientists monstrated that the hherto lled oxygenated muriatic acid, chlore, was a simple chemil, 1813, Gay-Lsac and Davy would return to make the same disvery workg separately: the disvery of of batn volumGay-Lsac also ma an important ntributn to stoichmetric laws.
