GAY-LSAC’S LAW: INTRODUCTN, FORMULA AND DERIVATN

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.

WHAT IS A REAL LIFE APPLITN THAT MONSTRAT GAY-LSAC'S GAS LAW?

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. 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).

This example illtrat why you shouldn’t cerate aerosol \({{\rm{T}}_{\rm{1}}}{\rm{ = 25^\circ C = 298\, K}}\)\({{\rm{T}}_{\rm{2}}}{\rm{ = 845^\circ C = 1118\, K}}\)Next, plug the numbers to Gay-Lsac’s Law and solve for \({{\rm{P}}_{\rm{1}}}{{\rm{T}}_{\rm{2}}}{\rm{ =}}{{\rm{P}}_{\rm{2}}}{{\rm{T}}_{\rm{1}}}\)\(\left( {{\rm{3}}{\rm{.

Cookg of food si prsure okers is solely based on Gay Lsac’s Law (the relatnship between temperature and prsure). It is dangero to dispose of an aerosol n by ceratn bee heatg a prsurized aerosol n (such as a odorant) creas the prsure exerted by the gas on the walls of the ntaer (owg to Gay-Lsac’s Law) and n rult an explosn.

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.

The example problems e Gay-Lsac's law to fd the prsure of gas a heated ntaer as well as the temperature you would need to change the prsure of gas a ntaer. Gay-Lsac's law is a form of the ial gas law which gas volume is kept volume is held nstant, prsure of a gas is directly proportnal to s ual equatns for Gay-Lsac's law are P/T = nstant or Pi/Ti = Pf/ reason the law works is that temperature is a measure of average ketic energy, so as the ketic energy creas, more particle llisns occur and prsure creas. To solve the problem, jt work through the followg steps:The cylr's volume remas unchanged while the gas is heated so Gay-Lsac's gas law appli.

Gay-Lsac's gas law n be exprsed as:Pi/Ti = Pf/TfwherePi and Ti are the ial prsure and absolute temperaturPf and Tf are the fal prsure and absolute temperatureFirst, nvert the temperatur to absolute = 27 C = 27 + 273 K = 300 KTf = 77 C = 77 + 273 K = 350 KUse the valu Gay-Lsac's equatn and solve for = PiTf/TiPf = (6 atm)(350K)/(300 K)Pf = 7 atmThe answer you rive would be:The prsure will crease to 7 atm after heatg the gas om 27 C to 77 C.

Charl’ LawCharl’s law, disvered by Jacqu Charl (1746-1823) 1787 and refed by Joseph Louis Gay-Lsac (1778-1850) 1808, stat that at nstant prsure, the volume is directly proportnal to absolute temperature, for a fixed mass of a gas:.

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. He later wrote, “If one were not animated wh the sire to disver laws, they would often pe the most enlightened attentn.” 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. 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].

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.
