Sublimation: A solid changing directly into a gas without going through the liquid phase. Energy is added. Temperature is raised.

Melting: A solid changing into a liquid when energy is added. The temperature is raised.

Vaporization: A liquid changing into a gas when energy is added. The temperature is raised.

Freezing: A liquid changing into a solid when energy is removed. Temperature is lowered.

Condensation: A gas changing into a liquid when energy is removed.

Deposition: A gas changing directly into a solid without going through the liquid phase. Energy is removed. Temperature is lowered.
