Born December 6, 1778 Died May 8, 1850 Was born in Saint-Léonard-de-Noblat, France Was a French Chemist He made two balloon ascensions in 1804 to test the vibration of the earth’s magnetic felid and to test the composition of the atmosphere He improved the methods of analyzing gas mixtures In 1802 discovered that gas at a constant pressure expands Formulated the law of combining volumes ** This law states that pressure is directly proportional to the absolute temperature. The equation for this law is: P1/T1= P2/T2. The law of combining volumes state that volumes of gases interact giving gas products small whole number ratios.

 * Gay-Lussac Law:

**Question:** The gas in a container is at a pressure of 3.00 atm at 25C. Directions on the container warn the user not to keep it in a place where the temperature exceeds 52C. What would the gas pressure in the container be at 52C? **Given:** P1 of gas = 3.00atm T1 of gas = 25C + 273 = 298K T2 of gas = 52C + 273 = 325k **Unknown**: P2 of gas in atm Equation: P1/T1 = P2/T2 P2 = P1T2/T1 P2 = ( 3.00atm)(325K) = 975atm = **//3.27atm//** _____________________ _________   298K 298
