| Chemical Property | A property of matter that describes a substance's ability to participate in chemical reactions |
| Gas | A form of matter taht does not have a definite volume or shape |
| Liquid | The state of matter that has a definite volume but not a definite shape |
| Solid | The state of matter in which the volume and shape of a substance are fixed |
| States of Matter | The physical forms of matter, which include solid, liquid, and gas |
| Surface Tension | The force that acts on the surface of a liquid and that tends to minimize the area or the surface |
