Two tanks are initially separated from each other via an A valve. Tank I contains 1 ft3 of air at 100 psia and 150 ° F.
Tank II contains a mixture of N2 and O2 with 95% N2 at 200 psia and 200 ° F. The valve is opened allowing the contents of the two tanks mix. After complete mixing, it was found that the percentage of N2 in the gas
is 85%.
Calculate the volume of tank II.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
