| Chemistry | study of matter and its reactions |
| Matter | anything that has mass and takes up space |
| Properties | characteristics used to describe a substance |
| What are the 4 basic properties of matter? | mass, volume, weight, density |
| Characteristics used to describe an object | properties |
| What are examples of matter? | water , air |
| Chemist | a person who studies matter |
| Gas | phase of matter that has no definite shape or volume |
| Liquid | phase of matter with a definite volume BUT no definite shape |
| Phase | form of matter |
| Solid | phase of matter with a definite shape and volume |
| Condensation | change from a gas to a liquid(drops of water) |
| Evaporation | change from a liquid to a gas at the surface of a liquid(disappear) |
| Freezing | change from a liquid to a solid |
| Melting | change from a solid to a liquid |
| Phase Change | a change in matter from one phase to another |
| Chemical change | change that produces a NEW SUBSTANCE |
| Physical Change | change that does not produce a new change |
| State of matter | physical form of matter |
| Plasma | fourth state of matter that is rare on Earth but plentiful in other parts of the universe |
| Sublimation | a change from a solid to a gas |
| Physics | deasl with the study of energy and matter and how they interact |
| Specialization | studying or working in one area of subject |
| Physicist | person who studies different forms of energy and the ways that energy and matter interact |
| Mass | amount of matter in an object |
| Weight | measure of the pull of gravity |
| Volume | amount of space or matter an object takes up |
| Density | comparison of mass to volume |
| Formula for density | mass divided by volume |
| Formula for volume of a solid | length x width x height |
