| Kinetic Energy | the energy an object has due to its motion |
| Temperature | a measure of the average kinetic energy of all the particles in an object |
| Thermal energy | the total potential and kinetic energies of an object |
| Melting | the temperature at which the solid state changes to the liquid state |
| Freezing | the temperature at which matter changes from the liquid state to the solid state |
| Vaporization | the change in state of a liquid into a gas |
| Boiling | the temperature at which a liquid becomes a gas |
| Evaporation | vaporization that occurs only at the surface of a liquid |
| Sublimation | the change of state from a solid to a gas without going through the liquid state |
| Deposition | the change of state of a gas to a solid without going through the liquid state |
| Condensation | The change of state from a gas to a liquid |
