<Chapter 9 Review> Composition of the air Roughly 78% N 2 , 21 % O 2 , 1% Ar. CO 2 IS 380 PPM AND INCREASING. Pressure and Temperature of Gases and the Ideal Gas Law Pressure is defined as force/area measured in atm, bar, pascal, and torr. The empirical gas laws of Boyles, Charles, and Avogadro combine to give the ideal gas law: PV=nRT. Gaseous Mixtures are describes by Dalton’s Law P A = n A RT/V X A = N A / n tot P A = X A P tot The Kinetic Theory of Gases Molecules are assumed to be widely separated point masses that interact only during collisions, moving randomly with a distribution of speeds, and experience elastic collisions with walls The square of the speed is the sum of the squares of the velocity components U 2 = v 2 x + v 2 y + v 2 z The rate of momentum transfer = (rate of collisions along any axis) × (momentum transfer per collision) The total number of wall collisions relates the pressure to the average kinetic energy per molecules: PV = (1/3) Nm u 2 The kinetic theory of gases predicts the ideal gas law from a simple
