| solid | A state of matter that has a definite shape and a definite volume |
| crystalline solid | A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern |
| amorphous solid | A solid made up of particles that are not arranged in a regular pattern |
| liquid | A state of matter that has no definite shape but has a definite volume |
| fluid | A substance that can easily flow |
| surface tension | The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together |
| viscosity | A liquid’s resistance to flowing |
| gas | A state of matter with no definite shape or volume |
| melting | The change from the solid to the liquid state of matter |
| melting point | The temperature at which a substance changes from a solid to a liquid |

| boiling point | The temperature at which a substance changes from a liquid to a gas |
| condensation | The change from the gaseous to the liquid state of matter |
| sublimation | The change in state from a solid directly to a gas without passing through the liquid state |
