| kinetic energy | energy in motion. |
| pressure | the force applied to a unit area of surface |
| absolute zero | a temperature of 0 kelvins |
| charles law | the physical law that the volume of a fixed mass of gas held at a constant pressure varies directly with the absolute temperature |

| heat of fusion | the amount of energy required to change a substance from the solid phase to the liquid phase at its melting point |
| exothermic | releases energy |
| vaporization | the change from a liquid to a gas |
| heat of vaporization | the amount of energy required for the liquid at its boiling point to become a gas |
