| solid | A state of matter that has a definite volume and a definite shape. |
| liquid | A state of matter that has a definite volume but no definite shape. |
| gas | A state of matter with no definite shape or volume. |
| melting point | The temperature at which a substance changes from a solid to a liquid. |
| viscosity | The resistance of a liquid to flowing. |
| temperature | The measure of the average kinetic energy of the particles in a substance. |
| pressure | The force exerted on a surface divided by the total area over which the force is exerted; also the force of a gas's outward push divided by the area of the walls of the container. |
| directly proportional | A term used to describe the relationship between two variables whose graph is a straight line passing through the point (0, 0). |
| vary inversely | A term used to describe the relationship between two variables whose graph forms a curve that slopes downward from left to right. |
| thermal energy | The total energy of a substance's or material's particles due to their movement or vibration. |
| melting | The change from the solid to the liquid state of matter. |
| freezing | The change in state from a liquid to a solid. |
| vaporization | The change from the liquid to the gaseous state of matter |
| evaporation | The process that occurs when vaporization takes place only on the surface of a liquid. |
| 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. |
| 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. |
