the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
