JOSEPH LOUIS GAY-LSAC

French chemist Joseph Louis Gay-Lsac proposed two fundamental laws of gas the early 19th century. While one is generally attributed to a fellow untryman, the other is well known as Gay-Lsac’s law.

Joseph Louis Gay-Lsac (1778–1850) grew up durg both the French and Chemil Revolutns.

Gay-Lsac’s own reer as a profsor of physics and chemistry began at the Éle Polytechnique. 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.

The latter law was published by Gay-Lsac 1802, [2] but the article which he scribed his work, he ced earlier unpublished work om the 1780s by Jacqu Charl. The rat between the volum of the reactant gas and the gaseo products n be exprsed simple whole example, Gay-Lsac found that two volum of hydrogen and one volume of oxygen would react to form two volum of gaseo water.

Based on Gay-Lsac's rults, Ameo Avogadro hypothized that, at the same temperature and prsure, equal volum of gas nta equal numbers of molecul (Avogadro's law). E., 100mL and 50mL) bear a simple rat of law of bg gas was ma public by Joseph Louis Gay-Lsac 1808.

JOSEPH-LOUIS GAY-LSAC

Some troductory physics textbooks still fe the prsure-temperature relatnship as Gay-Lsac's law. [6] [7] [8] Gay-Lsac primarily vtigated the relatnship between volume and temperature and published 1802, but his work did ver some parison between prsure and temperature.

[9] Given the relative technology available to both men, Amontons uld only work wh air as a gas, whereas Gay-Lsac was able to experiment wh multiple typ of mon gas, such as oxygen, nrogen, and hydrogen.

GAY LSAC LAW FORMULA

[10] Volume-temperature lawRegardg the volume-temperature relatnship, Gay-Lsac attributed his fdgs to Jacqu Charl bee he ed much of Charl's unpublished data om 1787 – hence, the law beme known as Charl's law or the Law of Charl and Gay-Lsac. [12] The value of the rate of expansn α is approximately the same for all gas and this is also sometim referred to as Gay-Lsac's Law.

The macrospic gas laws were found to be nsistent wh atomic and ketic theory, though wh much scepticism over the realy of such a Louis Gay-Lsac was a French chemist and physicist.

GAY-LSAC'S LAW DEFN

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. Charl as “Charl’s law, ” was the first of several regulari the behavur of matter that Gay-Lsac tablished. ” Of the laws Gay-Lsac disvered, he remas bt known for his law of the bg volum of gas (1808).

GAY LSAC'S LAW

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].

GAY-LSAC'S LAW

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. 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.
