| The 3 states of matter | Liquid, Solid, and Gas |
| Liquid | Water |
| Gas | Oxygen |
| Solid | Ice |
| Temperature | How fast particles are moving |
| Evaporation | Vaporization that occurs at the surface of a liquid below its boiling point. |
| Melting | Solid to a Liquid |
| Freezing | Liquid to a Solid |
| Matter | Anything that has volume and mass. |
| Volume | The amount of space that something occupies. |
| Meniscus | The curve at a liquid's surface by which you measure the volume of the liquid |
| Mass | The amount of matter that something is made of; its value does not change in space (universe) |
| Gravity | A force of attraction between objects that is due to their masses |
| Weight | A measure of the gravitational force exerted on an object, usually by Earth |
| Newton | The SI unit of force |
| Inertia | The tendency of all objects to resist any change in motiion. |
| Physical property | Property that can be observed without changing the identity of the matter |
| Chemical property | Describes a substance based on its ability to change into a new substance with different properties. |
| Physical change | The identity of the matter is not changed. |
| Chemical change | One or more substances are changed into entirely new substances with different properties; cannot be reversed using physical means. |
| Solid | Matter has a definite shape and volume |
| Liquid | Matter takes the shape of its container but has a definite volume. |
| Gas | Matter changes in both shape and volume |
| Pressure | The amount of force exerted on a given area; force/area. |
| Boyle's law | For a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases. |
| Charle's law | For a fixed amount of gas at a constant pressure, the volume of a gas increases as its temperature increases. |
| Plasma | Matter that does not have a definite shape or volume and whose particles have broken apart. |
| Change of State | The conversion of a substance from one physical form to another |
| Endothermic | A change in which energy is released or removed. |
| Exothermic | A change in which energy is released or removed. |
| Vaporization | The change of state from a liquid to a gas; includes boiling and evaporation. |
| Boiling | Vaporization that occurs throughout a liquid. |
| Condensation | Change of state from a gas to a liquid. |
| Sublimation | Change of state from a solid directly to a gas |
