Joseph-Louis Gay-Lsac, 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 * gay lussac history *
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.
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.
JOSEPH-LOUIS GAY-LSAC

Charl as “Charl’s law, ” was the first of several regulari the behavur of matter that Gay-Lsac tablished. 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 Law is a Gas Law which Stat that the Prsure of a Gas (of a Given mass, kept at a nstant Volume) Vari Directly wh s Absolute Temperature. * gay lussac history *
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).
GAY-LSAC’S LAW
Gay-Lsac - November 1978 * gay lussac history *
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.
GAY-LSAC'S LAW—ITS CENTENARY
GAY-LUSSAC';S law regardg the posn of gas by volume was ma known about a hundred years ago. The paper which he elaborated , havg been read to the Société philomatique on December 31, 1808, was published the Mémoir la Société d'Arcil the followg year. Sce then the law has e to have a history of s own. Chemists were at a loss and ma many efforts to get and the atomic theory to su one another, and the place of the law science, though not now likely to change, was for long unsettled and dub. * gay lussac history *
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.

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. 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.

SCIENTIST OF THE DAY - JOSEPH LOUIS GAY-LSAC
Joseph Louis Gay-Lsac, a French chemist, was born Dec. 6, 1778. 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... * gay lussac history *
It may be of tert to prent the publitn of the papers agast a sle of Gay-Lsac's life span, omtg the first twenty-two years, when, unrstandably, he published nothg. AbstractGAY-LUSSAC';S law regardg the posn of gas by volume was ma known about a hundred years ago. 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 LAW — OVERVIEW & FORMULA - EXPII
Gay-Lsac's law stat that the prsure of a gas is directly proportnal to s temperature Kelv, given that the volume stays nstant. * gay lussac history *
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. Joseph Louis Gay-Lsac (December 6, 1778 – May 9, 1850) was a French chemist and physicist whose disvery of the law of bg volum of gas chemil reactns paved the way for our unrstandg of molecul and atoms. In 1789, at the begng of the French Revolutn, his parents found necsary to keep Gay-Lsac at home, where he received his early tn.
GAY-LSAC’S LAW OF BG VOLUM
* gay lussac history *
Gay-Lsac and fellow scientist Jean-Baptiste Bt were missned by the French ernment, at the stigatn of Berthollet and Laplace, to make an ascent a hot air balloon to take measurements of the earth's magic field and perform other experiments.
JOSEPH LOUIS GAY-LSAC AND HIS WORK ON GAS
atom - Atom - Dalton, Bohr, Rutherford: English chemist and physicist John Dalton extend Prot’s work and nverted the atomic philosophy of the Greeks to a scientific theory between 1803 and 1808. His book A New System of Chemil Philosophy (Part I, 1808; Part II, 1810) was the first applitn of atomic theory to chemistry. It provid a physil picture of how elements be to form pounds and a phenomenologil reason for believg that atoms exist. His work, together wh that of Joseph-Louis Gay-Lsac of France and Ameo Avogadro of Italy, provid the experimental foundatn of atomic chemistry. On the basis of the law of fe proportns, * gay lussac history *
In orr to take readgs at even greater heights, Gay-Lsac ma another ascent, this time alone, and was able to achieve an elevatn of seven thoand meters, a rerd for that time.
JOSEPH GAY-LSAC SUMMARY
Durg this ascent, Gay-Lsac was able to brg back sampl of air, and found their posn to be the same as the air at the earth's surface. In 1805, Gay-Lsac acpanied Alexanr von Humboldt on a year-long tour of Europe, durg which he met many of the famo scientists of his day, cludg Alsandro Volta. In 1807, a year after Gay-Lsac's return to France, Berthollet tablished a society of scientists lled the Societe d'Aucuiel.
