| Term | Definition |
|---|---|
| Anything that takes up space and has mass- | Matter |
| The most common state of matter in space- | Plasma |
| The three most common forms of matter on earth are- | Solids, liquids,and gases |
| The amount of matter in a object- | Mass |
| The amount of space that matter occupies- | Volume |
| Density of a given substance remains- | Constant -regardless of the size of the sample. |
| The two main factors that determine the state of matter are particle- | Motion and particles Forces. |
| Particles move in a straight line until they- | Collide- with something. |
| Atoms contain positively charged- | protons-and negatively charged -electrons. |
| As the motion of particles - | Increase,particles move farther apart. |
| The matter that has a definite shape and a definite volume | Solid |
| Particles in a solid simply back and forth in place- | Vibrate |
| Matter with a definite volume but no definite shape - | Liquid |
| The particle motion in the liquid state of a material is than the particle motion in the solid state- | Faster |
| A measurement of a liquids resistance to flow- | Viscosity |
| As a liquid becomes warmer,particles begin to move faster and the attractive forces between them get- | Weaker |
| Molecules at the surface of a liquid have - ,the uneven forces acting on the particles on the surface of a liquid- | Surface- Tension |
| Matter that has no definite volume and no definite shape- | Gas |
| The gas state of a substance that is normally a solid or a liquid at room temperature is called- | Vapor |
| Rocks- | Solid |
| Air- | Gas |
| Water- | Liquid |
| Steam- | Liquid |
| Tree- | Solid |
| Gasoline- | Liquid |
