| Liquid | matter that has a definite volume but no definite shape |
| Fluid | A substance that flows |
| Surface tension | the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together |
| Viscosity | the resistance of a liquid to flowing |
| Melting | change from a solid to a liquid |
| Melting Point | the temperature at which a substance changes from a solid to a liquid |
| Freezing | the change in state from a liquid to a solid |
| Freezing point | the temperature at which a substance changes from a liquid to a solid |
