| Term | Definition |
|---|---|
| Matter | anything that has volume and mass |
| Newton | the SI unit of force. |
| physical change | a change that affects one or more physical properties of a substance; most physical changes are easy to undo. |
| gas | the state in which matter changes in both shape and volume. |
| volume | the amount of space that something occupies or the amount of space that something contains |
| inertia | the tendency of all objects to resist any change in motion. |
| chemical change | a change that occurs when one or more substances are changed into entirely new substances with different properties; cannot be reversed using physical means |
| pressure | the amount of force exerted on a given area. |
| mass | the amount of matter that something is made of; its value does not change with the object’s location in the universe. |
| physical property | a property of matter that can be observed or measured without changing the identity of the matter. |
| state of matter | the physical forms in which a substance can exist; states include solid, liquid, gas, and plasma. |
| plasma | the state of matter that does not have a definite shape or volume and whose particles have broken apart |
| gravity | a force of attraction between objects that is due to their masses. |
| density | the amount of matter in a given space; mass per unit volume. |
| solid | the state in which matter has a definite shape and volume. |
| change of state | the conversion of a substance from one physical form to another. |
| weight | a measure of the gravitational force exerted on an object, usually by Earth. |
| chemical property | a property of matter that describes a substance based on its ability to change into a new substance with different properties. |
| liquid | the state in which matter takes the shape of its container and has a definite volume. |
| Melting | the change of state from a solid to a liquid |
