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

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.

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.

GAY-LSAC'S LAW DEFN

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.

WHAT IS GAY-LSAC’S LAW AND WHY IS IMPORTANT METEOROLOGY?

" 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.

Joseph Louis Gay-Lsac (1778–1850) was a French physicist and chemist bt known for two laws of physics about gas.

This beme known as Gay-Lsac’s Law and is important for unrstandg chemil reactns of gas wh our atmosphere.

JOSEPH-LOUIS GAY-LSAC

Gay-Lsac also published a law about gas expansn by volume occurrg learly as a functn of temperature. Sometim creded as another of Gay-Lsac’s laws, is more rrectly lled Charl’ Law (and Gay-Lsac was one of those who gave cred where was due). 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’S LAW: INTRODUCTN, FORMULA AND DERIVATN

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.

GAY LSAC’S LAW

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 LAW—ITS CENTENARY

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.

WHAT IS THE GAY-LSAC'S LAW?

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.

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.

'WE'RE NOT HIDG': GAY AND LBIAN RSIANS SAY A CULTURAL SHIFT IS UNRWAY

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. 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. Be sure to nvert Fahrenhe and Celsi temperature to Kelv when solvg Gay-Lsac’s law problems. This is bee when a prsurized aerosol n (such as a odorant) is heated, the prsure exerted by the gas on the walls of the ntaer creas(owg to Gay-Lsac’s Law) and n rult an explosn.

The science behd prsure okers is solely based on the relatnship between temperature and prsure (Gay Lsac’s Law).
