At constant volume, for a fixed number of moles of a gas the pressure of the gas increases with rise — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Pressure exerted on the walls of the container by gas molecules is equal to the change in momentum per unit time and area. At constant volume, for a fixed number of moles of a gas, with increase in temperature, the pressure of the gas increases due to increase in their average molecular speed. This increase leads to change in momentum during collisions.
