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

When temperature increases at constant volume, the average speed of the gas molecules increases. This causes the molecules to strike the walls more frequently (higher collision rate) and with greater momentum per impact ($p = mv$). Both of these factors contribute to the increased macroscopic pressure. Therefore, correct answer is C,D.
