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. 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. 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. 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.

JOSEPH GAY-LSAC SUMMARY

” 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 (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.

JOSEPH LOUIS GAY-LSAC BGRAPHY, LIFE, INTERTG FACTS

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. 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.

On the basis of Dalton's and Gay-Lsac's work, Ameo Avogadro proposed the hypothis that equal volum of gas nta equal volum of molecul, one of the rnerston of morn chemistry. In 1815, Gay-Lsac rried out some important rearch on de and s pounds, although Brish scientist Humphrey Davy is generally creded wh havg intified de as an element.

In 1802, Gay-Lsac first formulated the law that a gas expands learly wh a fixed prsure and risg temperature (ually better known as Law of Charl and Gay-Lsac). The proper pennce of the expansn efficient on the temperature self was also exprsed rrectly by Gay-Lsac, a rult that Dalton's more c experiments failed to tect.

In 1815, the rivalry that had been generated between Gay-Lsac and Davy over the disvery of elements once aga surfaced a qut to terme the nature of what would bee known as de. The lorful story of Davy's trip to Europe at the time, and his examatn of sampl of de g a portable laboratory, bolsters his claim to disvery popular lerature, although Gay-Lsac appears to have announced his rults first.

Young Gay-Lsac received his early tn at home unr the directn of the abb� Bourdix and other masters, and 1794 was sent to Paris to prepare for the �le Polytechnique, to which he was admted at the end of 1797 after a brilliant examatn.

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.

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.

Also around this time, he embarked on an amb seri of experiments volvg phenomena as diverse as the behavr of fluids and vapors, and the improvement of thermometers and 1805-06, Gay-Lsac embarked on a European tour wh the scientific explorer Alexanr von Humboldt. He also tablished that hydrogen and oxygen be by volume the rat 2:1 to form the laws Gay-Lsac disvered, Gay-Lsac remas bt known for his law of the bg volum of gas (1808).

Gay-Lsac’s approach to the study of the matter was nsistently volumetric rather than gravimetric, ntrast to that of his English ntemporary John 1807, a year after Gay-Lsac’s return to France, Berthollet tablished a society of scientists lled the Societe d’Aucuiel.
