Charles’ Law Boyle’s Law V = k T PV = k P and V

Charles’ Law Boyle’s Law V = k T PV = k P and V change n, R, T are constant Gas Law Calculations Ideal Gas Law PV = n. RT P, V, and T change n and R are constant Combined Gas Law PV = k T T and V change P, n, R are constant

RT Big = small + height Graham’s Law Gay-Lussac P 1 = P 2 T 1 = T 2 Ideal Gas Law Density P 1 = P 2 T 1 D 1 = T 2 D 2 diffusion vs. effusion Dalton’s Law Partial Pressures 1 atm = 760 mm Hg = 101. 3 k. Pa R = 0. 0821 L atm / mol K PT = P A + P B

Scientists • Evangelista Torricelli (1608 -1647) – Published first scientific explanation of a vacuum.

Scientists • Evangelista Torricelli (1608 -1647) – Published first scientific explanation of a vacuum. – Invented mercury barometer. • Robert Boyle (1627 - 1691) – Volume inversely related to pressure (temperature remains constant) • Jacques Charles (1746 -1823) – Volume directly related to temperature (pressure remains constant) • Joseph Gay-Lussac (1778 -1850) – Pressure directly related to temperature (volume remains constant)
