The volume of a gas is held constant while its temperature is raised. The pressure the gas exerts on — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

As temperature increases at constant volume, average molecular speed and kinetic energy increase. This causes molecules to collide with the walls of the container with higher velocity (and thus greater momentum transfer per collision) and to strike the walls more frequently. Molecular mass remains constant, and collisions with the walls are assumed to be elastic.
