Question 1

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?

A

The average force exerted per collision doubles, while the frequency of collisions with the walls remains constant.

B

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​.

C

The frequency of collisions with the walls doubles, while the average force exerted per collision remains constant.

D

Both the frequency of collisions with the walls and the average change in momentum during each collision double.
