Yes.

Explanation:

The heats of fusion and vaporization are the amounts of energy used to change phases (solid/liquid and liquid/gas respectively). WHAT that energy is really doing is making the molecules move faster (kinetic energy) until they can no longer maintain their connections as either a solid or liquid.

Continued heating of a gas also continues to increase the kinetic energy. A gas in an enclosed space exhibits increasing pressure (force per unit area) on a container due to the ‘collisions’ of the moving gas molecules against the container surface.
