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.

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. Gay-Lsac proved to be an exemplary stunt durg his studi there om 1797 to 1800.

The society’s first volume of memoirs, published 1807, clud ntributns om 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.

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 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.

GAY-LSAC'S LAW

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.

GAY-LSACSCIENTIST AND BOURGEOIS

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.

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. Gay-Lsac was a key figure the velopment of the new science of volumetric analysis. 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.

GAY LSAC'S LAW IS NOT VALID THE CHEMIL REACTN:

In 1831 Gay-Lsac was elected to the Chamber of Deputi and 1839 received a peerage. 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 this article, we’ll go over Gay Lsac’s Law tail, cludg s formula and rivatn. 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. When a prsurized aerosol n (such as a odorant n or a spray-pat n) is heated, the rultg crease the prsure exerted by the gas on the ntaer (owg to Gay-Lsac’s law) n rult an explosn. The law of Gay-Lsac is a variant of the ial gas law where the volume of gas is held nstant.

GAY-LSAC'S GAS LAW EXAMPL

P / T = nstant or Pi / Ti = Pf / Tf are the standard lculatns for Gay-Lsac ‘s law. To learn more about Gay-Lsac’s law and other gas laws, such as Charl’ law, register wh BYJU’S and download the mobile applitn on your smartphone.

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.

GAY LSAC'S LAW

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.

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).

Other ways of wrg Gay-Lsac's law make easy to solve for the prsure or temperature of a gas:. Many scholars nsir Gay-Lsac to be the first to formulate Amonton's law of prsure-temperature. Gay-Lsac is also creded for other gas laws, which are sometim lled "Gay-Lsac's law.

GRAPHS OF GAY-LSAC'S LAW

" For stance, Gay-Lsac stated that all gas have the same mean thermal expansivy at nstant prsure and temperature. 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. In this article, we will learn about Gay-Lsac's law, which explas the relatnship between temperature and prsure for article vers Gay-Lsac's LawFirst, we will do an overview of the ponents of Gay-Lsac's law (ial gas, temperature, and prsure)Then, we will learn about Gay-Lsac's law and unrstand what meansNext, we will look at the equatn that is paired wh the law and e an exampleGay-Lsac's Law OverviewBefore we learn about Gay-Lsac's law, let's do a brief overview of the ponents volved: ial gas, temperature, and prsure.

Now that we've learned about the key players, let's talk about Gay-Lsac's LawGay-Lsac's Law StatementGay-Lsac's Law stat that the prsure of a gas (wh a given mass and nstant volume) will be proportnal to the temperature of the other words, the prsure exerted by a gas is proportnal to s temperature when mass and volume are Lsac's Law ExplanatnAs we talked about earlier, temperature tells how much ketic energy a gas has, which turn tells how fast is movg. 1-Diagram of Gay-Lsac's lawOn the right-hand si, the gas particl have an ial temperature and prsure (P1). Essentially, Gay-Lsac's law stat that sce the temperature is creasg, the prsure should also crease by a proportnate our troductn, we talked about tire prsure creasg wh the weather.

Gay-Lsac is bt known for his chemil work but also ma important ntributns to other physil scienc and technology. Joseph Louis Gay-Lsac (1778–1850) lived through three revolutns France and his life reflected the social transformatns takg place around him.

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. The Gay-Lsac’s law monstrat the relatnship between the prsure and the temperature of an ial gas. This is the practil implitn of Gay-Lsac’s law that is ed for solvg gas problems.
