| A | B |
| Boiling | Vaporization that occurs on and below the surface of a liquid |
| Boiling Point | the temperature at which a substance changes from a liquid to a gas |
| Boyle's Law | The relationshiop between the pressure and volume of a gas at constant temperature; when volume increases, pressure decreases |
| Charles' Law | The relationship between the temperature and volume of a gas a constant pressure; when temperature increases, volume increases |
| Condensation | the change of state from a gas to a liquid |
| Evaporation | the process that occurs when vaporization takes place only on the surface of a liquid |
| Freezing | change from liquid to a solid |
| Gas | a state of matter with no definite shape or volume |
| Graph | a diagram that shows how two variables are related |
| Liquid | a state of matter that has a definite volume but no definite shape |
| Melting | change from a solid to a liquid |
| Melting Point | the temperature at which a substance changes from a solid to a liquid |
| Pressure | the force pushing on an area or surface |
| Sublimation | a change directly from the solid to the gaseous state without becoming liquid |
| Temperature | the average amount of energy of motion in the molecules of a substance |
| Thermal Energy | the total energy of a substance's particles due to their movement or vibration |
| Vaporization | the change from a liquid to a gas |
| Viscosity | a liquid's resistance to flow |
