GAY-LSAC’S LAW

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. 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.

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. 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.

JOSEPH LOUIS GAY-LSAC

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 II. TöRVéNYE

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.

LEY GAY-LSAC: FICIóN, FóRMULA Y EJEMPLOS

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.

La senda legge di Gay-Lsac riguarda il portamento i gas iali nelle trasformazni isore, e scrive la relazne tra temperatura e prsne di un gas qualsiasi quando è soggetto a una trasformazne a volume stante. Tra un attimo prenteremo enunciato e formula lla senda legge di Gay-Lsac, e vedremo quante analogie prenta rispetto alla prima. ;)La senda legge di Gay-Lsac per le trasformazni isoreSappiamo che le tre granzze che scrivono lo stato termodami di un gas sono prsne, temperatura e volume.

Abbiamo già studiato due lle tre leggi che scrivono il portamento i gas perfetti, quando si subisno una trasformazne cui una lle tre variabili di stato rimane stante e le altre due sono libere di variare:- la legge di Boyle ci dice e si porta un gas iale quando è sottoposto a una trasformazne isoterma (a temperatura stante);- la prima legge di Gay-Lsac ci dice e si porta un gas iale quando subisce una trasformazne isobara (a prsne stante);- la senda legge di Gay-Lsac scrive ciò che ac a un gas iale quando è soggetto a una trasformazne isora (a volume stante) ci rta che analizzare il terzo so, e sprire quale relazne ssiste tra temperatura e prsne quando un gas è sottoposto a una trasformazne a volume prima sa da fare è quadrare le trasformazni isore nel piano di Clapeyron, dove i valori di volume vengono lloti sull'asse x e quelli di prsne sull'asse y. Veniamo allora alla formulazne lla senda legge di Gay-Lsac:dove:- di la prsne l gas quando la sua temperatura è di 0 °C;- è il efficiente di dilatazne termi i gas;- è la temperatura prsa gradi senda legge di Gay-Lsac ci dice che, mantenendo il volume stante, la prsne varia learmente n la temperatura.

French chemist Joseph Louis Gay-Lsac proposed two fundamental laws of gas the early 19th century.

DEFINITIONS FOR GAY-LSACˌGEɪ LəˈSæKGAY-L·SAC

While one is generally attributed to a fellow untryman, the other is well known as Gay-Lsac’s law.

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.
