In terms of the kinetic theory of gases, explain why the pressure of a gas in a closed container increases when the gas is heated?

answered-by-expert Expert Answer

As the temperature of a gas is increased, its pressure increases due to the following reasons :

(i)  with an increase in temperature, the velocity of the gas molecules increases, and as such they strike the walls of the container more often than before.

(ii)  Due to an increased velocity, each impact is more powerful than before.
