| The state of matter in which materials have a definite volume and but not a definite shape. | Liquid |
| The state of matter in which a material has neither a definite shape or volume/ | Gas |
| The energy an object has due to its motion. | Kinetic Energy |
| The result of a force distributed over an area. | Pressure |
| A tempature of 0 Kelvins. | Absolute Zero |
| The direct proportion of the volume of a gas to its temperature if the pressure and the number of particles of the gas are constant. | Charles's Law |
| The inverse variation of the volume of a gas with its pressure if the temperature and the number of paricles are constant. | Boyle's Law |
| The reversible physical change that occurs when a substance changes from one state to another. | Phase Change |
| A description of a change in which a system aborbs energy from its surrondings. | Endothermic |
| The energy a substance must absorb in order to change from a solid to a liquid. | Heat of Fusion |
| The system releases energy to its surroundings. | Exothermic |
| The phase change in which a substance changes from a liquid to a gas. | Vaporization |
