A rigid vessel of fixed volume contains a fixed mass of an ideal gas. The absolute temperature of the gas is increased from T T\,T to 2T2T2T, which doubles the pressure of the gas.
Which statement correctly explains this doubling of pressure in terms of the behavior of the gas particles?
The average force exerted per collision doubles, while the frequency of collisions with the walls remains constant.
Both the frequency of collisions with the walls and the average change in momentum during each collision increase by a factor of 2\sqrt{2}2.
The frequency of collisions with the walls doubles, while the average force exerted per collision remains constant.
Both the frequency of collisions with the walls and the average change in momentum during each collision double.
