| A state of matter that has a definite volume and a definite shape. | Solid |
| A state of matter that has a definite volume but no definite shape | Liquid |
| A state of matter with no definite shape or volume. | Gas |
| A substance that is made up of crystals in which the particles are arranged in a regular, repeating patterns. | Crystalline Solid |
| small particles of matter | Atom |
| describes matter and indicates ability to change chemically; include acidity, basicity, combustibility, and reactivity | Chemical Property |
| two or more elements chemically combined in fixed ratio | Compound |
| The force exerted on a surface divided by the total area over which the forces exerted; also the force of a gas's outward push divided by the area of the walls of the container | Pressure |
| The relationship between the temperature and the volume of a gas at constant pressure; when temperature increases, volume increases | Charles' Law |
| The relationship between the pressure and volume of a gas at constant temperature; when volume increases, pressure decreases | Boyle's Law |
| A diagram that shows how to variables are related | Graph |
| A term used to describe the relationship between two variables whose graph is a straight line passing through the point | Directly Proportional |
| A term used to describe the relationship between two variables whose graph forms a curve that slopes downward from left to right | Vary Inversely |
| The total energy of a substance's or material's particles due to their movement or vibration | Thermal Energy |
| The change from a solid to a liquid state of matter | Melting |
| The change in state from a liquid to a solid | Freezing |
| The change from the liquid to the gaseous state of matter | Vaporization |
| The process that occurs when vaporization takes place only on the surface of a liquid | Evaporation |
| Vaporization that occurs on and below the surface of a liquid | Boiling |
| The temperature at which a substance changes from a liquid to a gas | Boiling Point |
| The change from the gaseous to the liquid state of matter | Condensation |
| The change in state from a solid directly to a gas without passing through the liquid state | Sublimation |
