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.

JOSEPH LOUIS 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.

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.

JOSEPH GAY-LSAC SUMMARY

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]. 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.

GAY-LSAC’S LAW

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.

SCIENTIST OF THE DAY - JOSEPH LOUIS GAY-LSAC

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.

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.

LEIS GAY-LSAC

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.

Gay-Lsac is well known to morn chemists for two laws, one relatg the volume of a gas to s temperature (volume creas learly wh temperature), and the send, lled the law of bg volum, which stat that when two gas be, their volum are the rats of small whole numbers. The law of bg volum uld be ed to support John Dalton's atomic theory, published the very same year, for if water nsists of two atoms of hydrogen and one of oxygen, then one might well expect that you would need two volum of hydrogen for every one of oxygen (assumg that equal volum of gas nta equal numbers of particl, and Amao Avogadro would offer this up as his own law, Avogadro's hypothis, 1811) the non-chemist, Gay-Lsac's reer as a balloonist might be of more tert.

GAY LSAC’S LAW

Wh fellow chemist Jean-Baptiste Bt, Gay-Lsac ma a balloon ascent of some 4 1804, llectg atmospheric sampl all the way, and the next year he ma a solo ascent and went even higher, settg an altu rerd of some 23, 000 feet that would stand for another 60 years. He also termed that the posn of the atmosphere do not change wh 1867, Louis Figuier published an image of the Bt/Gay-Lsac ascent that has proved que endurg balloong lore (send image); the illtratn has been much pied, even appearg on a tea rd (first image).

Além do s trabalho os gas, Gay-Lsac também realizou experimentos sobre a eletrólise da água, os quais acredava ter sberto a posição da água.

Joseph Louis Gay-Lsac (, [1][2], [3][4] French: [ʒɔzɛf lwi ɡɛlysak]; 6 December 1778 – 9 May 1850) was a French chemist and physicist. 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. The father of Joseph Louis Gay, Anthony Gay, son of a doctor, was a lawyer and prosecutor and worked as a judge Noblat Bridge.

1802 – Gay-Lsac first published the law that at nstant prsure, the volume of any gas creas proportn to s absolute temperature.

He is known mostly 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. Joseph Gay-Lsac’s father was a judge and was actually lled Antoe Gay, a small tate near her place of rince was lled Lsac. In November 1794 he went to Paris; due to fame many pupils were sent back home to their parents – Gay-Lsac was allowed to stay bee of his good mathematil skills.

Three years later, Gay-Lsac transferred to the Éle s Ponts et Chssé, and shortly afterwards was assigned to C. [3] They were able to measure a temperature drop of 1 °C per 174 metr of altu ascent, and Gay-Lsac and Alexanr von Humboldt were able to refute John Dalton‘s ia that atomic heavier gas sk, lighter atomic gas rise, and that the posn the higher atmosphere chang as a rult. In 1808 Gay-Lsac beme profsor of practil chemistry at the Éle polytechnique Paris 1808 and simultaneoly profsor of physics and chemistry at the Sorbonne, a post which he only rigned for the chair of chemistry at the Jard s Plant.

In 1830 Gay-Lsac was elected a foreign member of the Göttgen Amy of Science and 1832 he was elected to the Amerin Amy of Arts and Scienc. In 1802 he formulated the law of Gay-Lsac, acrdg to which gas expand learly wh creasg temperature if the prsure remas nstant. The efficient of volume crease, which Gay-Lsac measured for each gree of temperature crease, was 1/266 ( fact: 1/273).

Some well known scientists (Amontons, Lambert, Charl) had already prepared the Gay-Lsac law, but they had not yet termed the gree of expansn of the gas precisely enough. In 1807, Gay-Lsac rried out temperature experiments wh two rooms of equal size, nnected by a pipe and separable om each other.

LOUIS JOSEPH GAY-LSAC

Sce 1808 Gay-Lsac and Louis Jacqu Thénard tried to produce pure potassium and sodium om potassium hydroxi and sodium hydroxi, rpectively, g a voltic pile.

Gay-Lsac studied the de disvered 1811 by Bernard Courtois and showed that the chemil properti of de and chlore are siar. The French chemist Joseph Gay-Lsac \((1778-1850)\) tablished the relatnship between the prsure of a gas and s absolute temperature. Gay-Lsac’s Law stat that at nstant volume, the prsure of a given mass of gas vari directly wh the gas’s absolute temperature.

Gay-Lsac’s Law is very siar to Charl’s Law; the only difference is that a Charl’s Law experiment, the ntaer is flexible, whereas, a Gay-Lsac’s Law experiment, the ntaer is rigid. From Gay Lsac’s Law, we know that the prsure of a given mass of gas vari directly wh the gas’s absolute temperature. Hence, Gay-Lsac’s Law impli that for a gas of a fixed mass kept at a nstant volume, the ial prsure and temperature rat is equal to the rat of the fal prsure and temperature.
