| solid | The state of matter in which materials have a definite shape and a definite volume. |
| liquid | The state of matter in which a material has a definite volume but not a definite shape. |
| gas | The state of matter in which a material has neither a definite shape nor a definite volume. |
| kinetic energy | The energy that an object has due to its motion. |
| pressure | The result of force distributed over an area. |
| absolute zero | This temperature is equal to 0K on the Kelvin terperature scale. |
| Charles's law | States that the volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particle of the gas are constant. |
| Boyle's law | States that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant. |
| phase change | The reversible physical change that occurs when a substance changes from one state of matter to another. |
| vaporization | The phase change in which a substance changes from a liquid to a gas. |
| evaporation | The process that changes a substance from a liquid to a gas at temperatures below the substance's boiling point. |
| condensation | The phase change in which a substance changes from a gas or vapor to a liquid. |
| sublimation | The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first. |
| deposition | The phase change in which a gas or vapor changes directly into a solid without first changing into a liquid. |
| evaporation | When a substance changes to a gas at the surface of the liquid. |
| condensation | The phase change in which a gas becomes a liquid. |
| boiling | This process takes place throughout a liquid and leads to vaporization. |
| freezing | The phase change in which a liquid turns into a solid. |
| melting | The phase change from which a solid turns into a liquid. |
| plasma | This form of matter is made up of charged molecules. |
