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. 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.

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. 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. 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. 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.

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.

Sce his paper announcg the law he ced earlier unpublished work on this subject by Jacqu Charl, the law is ually lled Charl's Law, though some sourc e the exprsn Gay-Lsac's Law. 1804 – He and Jean-Baptiste Bt ma a hydrogen-balloon ascent; a send ascent the same year by Gay-Lsac alone attaed a height of 7, 016 metr (23, 018 ft) an early vtigatn of the Earth's atmosphere. Amás ocupar la cátedra Fïsi en la Universidad la Sorbona y ser también tedráti Quími en el Instuto Poléi París, Gay-Lsac ocupó algunos rgos polítis cierta importancia.

Aunque fueron s ley sobre los gas las que han provodo que Gay-Lsac pasara a la historia, el científi también sarrolló otras vtigacn important.

[JOSEPH LOUIS GAY-LSAC (1778-1850)]

El scubrimiento Gay-Lsac tablece que en cualquier momento e proco la relación entre la temperatura absoluta y la prión mantiene un valor nstante. La ley Gay-Lsac se apli a los gas ial, mientras que en los real se cumple n bastante precisión si la prión y la temperatura tienen valor bajos. Al igual que ocurrió n las vtigacn sobre el boro, Gay-Lsac y Humphry Davy volvieron a cidir a la hora prentar un hallazgo sobre el cloro.

La novedad aportada por Gay Lsac en 1809 era relacnar los volúmen los productos y reactivos en una reacción quími n as proporcn los elementos en putos diferent. Joseph Louis Gay-Lsac was a French scientist who studied both physics and chemistry; he is bt known for disverg that water was ma up of two parts hydrogen and one part oxygen.

The name Lsac me om a nearby hamlet, and Gay-Lsac’s father would e as part of his name legal documentatn, they both adopted as their name 1803. In 1798, Gay-Lsac began studyg at the ÉlePolytechnique., he transferred to the Éle s PontsetChssé hen the ÉlePolytechnique which beme a ary amy 1801.

1802 - Gay-Lsac pertama kali memkan hum Gay-Lsac, yang menyatakan bahwa jika massa dan volume gas tetap konstan maka tekanan gas mengkat sera lear ngan mengkatnya suhu.

Hum Gay-Lsac dapat mej kepada salah satu dari dua hum kimia yang dikemakan oleh Joseph Louis Gay-Lsac yang berhubungan ngan sifat-sifat gas. Hum Charl juga kadang-kadang disebut Hum Gay-Lsac at Hum Charl Gay-Lsac, karena Gay-Lsac lah yang pertama kali mempublikasikan penemuan i pada 1802.
