Answer:
the molecules strike the walls of the container more often.
Explanation:
The pressure of a gas refers to the force per unit area exerted on the walls of container by gas molecules.
Since the average kinetic energy of gas molecules increases as the temperature of the gas increases, the molecules of the gas tend to strike the walls of the container more often as the temperature of the gas increases.
Hence, the pressure of a gas increases due to an increase in temperature because the gas molecules strike the walls of the container more often.
