If O2(g) and H2(g) are in separate containers of equal pressure, volume and temperature, which one of these statements is true? The amount of moles in the O2 container is greater than that in the H2 container. There are more molecules in the H2 container than molecules in the O2 container.

The kinetic molecular theory of gases predicts pressure to increase as the temperature of a gas increases because: I. the average kinetic energy of the gas molecules increases. II. gas molecules collide more frequently with the container walls. III. there are more molecules per unit volume after raising the temperature. IV. the elasticity of the molecules increases. V. there are less molecules per unit volume after raising the temperature. a. I and II b. I and III c. II and...
