Which statement best describes what happens when two gas atoms—one large and dense, the other small and less dense—collide in a container?
The two atoms collide and keep their own kinetic energy. This inelastic collision between the two atoms does not change the total kinetic energy.
The larger, denser atom is able to transfer its energy to the smaller atom, so the overall kinetic energy stays the same.
The smaller, less dense atom is able to transfer its kinetic energy to the large atom, so the overall kinetic energy increases slightly.
None of these.
