JOSEPH LOUIS GAY-LSAC

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

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.

GAY-LSAC

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.

GAY-LSAC’S LAW

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 LAW DEFN

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.

CHARL AND GAY-LSAC’S LAW

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]. 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.

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 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 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.

Summary ‘One should not be miserly eher wh one's time or re’Gay-LsacScientific productivyAn appropriate place for an asssment of Gay-Lsac's ntributns to science is at the end of a book rather than the middle and this chapter therefore is ncerned rather to outle the range of Gay-Lsac's scientific work, which is far wir than one might thk, sce extends not only om the most theoretil to the most practil but also vers a spread of subject matter rangg om physics through chemistry to physlogy. We will beg wh the physil end of the spectm, which is where Gay-Lsac himself began after his mathematil trag at the Ele Polytechnique and his associatn wh Laplace, culmatg stutnal regnn as a member of the physics sectn of the Instute. The label of physicist, however, seems creasgly appropriate as Gay-Lsac's work beme almost exclively nsirg the tails of var aspects of Gay-Lsac's work might be eful to nsir his productivy over his whole reer.

It may be of tert to prent the publitn of the papers agast a sle of Gay-Lsac's life span, omtg the first twenty-two years, when, unrstandably, he published nothg. Gay-Lsac's law is an ial gas law which stat that at nstant volume, the prsure of an ial gas is directly proportnal to s absolute temperature ( Kelv). Gay-Lsac is sometim creded as beg the first to state Dalton's law, which says that the total prsure of a gas is the sum of the partial prsur of dividual gas.
