According to the kinetic theory of gases, the pressure of a gas is due to:
A)change of kinetic energy of molecules as they strike the wall
B)change of momentum of molecules as they strike the wall
C)average kinetic energy of the molecules
D)force of repulsion between the molecules
E)rms speed of the molecules

Question

Quizplus · Accepted Answer

The pressure of a gas is due to the change of momentum of molecules as they strike the wall, according to the kinetic theory of gases. The more the molecules collide with the walls of the container, the greater the pressure they exert, and the momentum of the molecules is related to their velocity and mass.
