The force on the walls of a vessel of a contained gas is due to:
A)repulsive force between gas molecules
B)slight loss in average speed of a gas molecule after collision with wall
C)change in momentum of a gas molecule due to collision with wall
D)elastic collisions between gas molecules
E)inelastic collisions between gas molecules

Question

Quizplus · Accepted Answer

The force on the walls of the vessel is due to the change in momentum of gas molecules when they collide with the wall. This change in momentum results in a force being exerted on the wall, which is the force experienced by the container. The other options (A, B, D, E) do not fully explain the force on the walls of the container.
