CHARL' LAW AND GAY-LSAC'S LAW

Learn about the theori of Charl’ Law and Gay-Lsac’s Law and explore exampl of the laws everyday life.

The four laws are Boyle’s Law, Charl’s Law, Gay-Lsac’s Law and Avogadro’s Law. Joseph Louis Gay-Lsac was a French chemist and physicist who disvered 1802 that if you keep the volume of a gas nstant (such as a closed ntaer), and you apply heat, the prsure of the gas will crease.

On Augt 24, 1804, Joseph Louis Gay-Lsac and Jean-Baptiste Bt ascend a hot air balloon to a height of 4, 000 meters altu orr to nduct scientific experiments on gas. The experiments led to Gay-Lsac's disvery that equal volum of all gas expand equally wh the same crease temperature.

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. Joseph Louis Gay-Lsac (1778–1850) grew up durg both the French and Chemil Revolutns.

JOSEPH LOUIS GAY-LSAC

Gay-Lsac’s own reer as a profsor of physics and chemistry began at the Éle Polytechnique. 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. This ncln subsequently beme known as Gay-Lsac’s law. 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

Featured image: Undated portra of Joseph Louis Gay-Lsac. 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.

Gay-Lsac was born at Sat-Léonard--Noblat, the partment of Hte-Vienne.

Of the three dghters and two sons of Antoe Gay-Lsac, he was the elst male child. Gay-Lsac's father was an officer of the kg, and his grandfather was a medil doctor. 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.

JOSEPH LOUIS GAY-LSAC'S HOT AIR BALLOON ASCENT, 1804

Gay-Lsac found that the rate at which all gas expand wh creasg temperature is the same. Gay-Lsac and Jean-Baptiste Bt ascend a hot air balloon 1804 (illtratn c. 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.

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. 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. Gay-Lsac was clud s membership.

GAY-LSAC AND BT HOT AIR BALLOON, 1804

Among the memoir published by the society clud Gay-Lsac's magic measurements ma durg his European tour, as well as work that he is perhaps bt remembered for, which he formulated what is today generally referred to Gay-Lsac's law of bg volum. Gay-Lsac extend his observatns to other gas, and noted that, when bg wh one another, they always do so by volume simple tegral rats. On the basis of Dalton's and Gay-Lsac's work, Ameo Avogadro proposed the hypothis that equal volum of gas nta equal volum of molecul, one of the rnerston of morn chemistry.

From 1808 Gay-Lsac was appoted profsor of physics at the Sorbonne, and 1809 he also beme profsor of chemistry at the Polytechnique.
