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.

JOSEPH GAY-LSAC SUMMARY

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.

BGRAPHY OF 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 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. The name Lsac me om a nearby hamlet, and Gay-Lsac’s father would e as part of his name legal documentatn, they both adopted as their name 1803.

In 1798, Gay-Lsac began studyg at the ÉlePolytechnique., he transferred to the Éle s PontsetChssé hen the ÉlePolytechnique which beme a ary amy 1801. He is known mostly for his disvery that water is ma of two parts hydrogen and one part oxygen (wh Alexanr von Humboldt), for two laws related to gas, and for his work on alhol-water mixtur, which led to the gre Gay-Lsac ed to measure alholic beverag many untri. 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.

The new assistant srcely me up to expectatns rpect of nfirmg certa theoretil views of his master's by the experiments set him to that end, and appears to have stated the discrepancy whout rerve; but Berthollet neverthels quickly regnized the abily displayed, and showed his appreciatn not only by sirg to be Gay-Lsac's "father science", but also by makg him 1807 an origal member of the Soc� d'Arcueil. Gay-Lsac's earlier rearch were mostly physil character and referred maly to the properti of gas, vapor-tensns, hygrometry, pillary, etc.

But this elevatn was not nsired sufficient by Gay-Lsac, who therefore ma a send ascent by himself on the 16th of September, when the balloon rose 7016 metr (about 23, 000 ft.

About this time Gay-Lsac's work, although he by no means entirely abandoned physil qutns, beme of a more chemil character; and three stanc brought him to direct rivalry wh Sir Humphry Davy. In the first se Davy's preparatn of potassium and sodium by the electric current spurred on Gay-Lsac and his llaborator Louis-Jacqu Th�nard, who had no battery at their disposal, to search for a chemil method of obtag those metals, and by the actn of red-hot iron on fed potash -- a method of which Davy admted the advantag -- they succeed 1808 preparg potassium, gog on to make a full study of s properti and to e , as Davy also did, for the rctn of boron om boracic acid 1809. The most plete list of Gay-Lsacs papers is ntaed the Royal Society's Catalogue of Scientific Papers, which enumerat 148, exclive of others wrten jotly wh Humboldt, Th�nard, Welter and Liebig.
