Answer» PRESSURE on the walls of the container is equal to the change of momentum per UNIT time per unit area. At constant volume, for a fixed number of moles of a gas, the pressure increases with RISE in temperature DUE to increase in average molecular speed. This increases the change in momentum during collisions.Explanation:I hope you understand...
