|---|---|
| _ is anything that takes up space and has mass. | Matter |
| _is the most common state of matter in space. | Plasma |
| The three of the most common forms of matter on earth are: | Solids ,Liquids, and Gases |
| _is the amount of matter in an object. | Mass |
| _is the amount of space that matter occupies. | Volume |
| Density of a given substance remains _ regardless of the size of the sample. | Constant |
| The two main factors that determine the state of matter are: | Particle motion and particle forces |
| Particles move in a strait line until they_ with something. | Collide |
| Atoms contain contain positively charged _ and negatively charged_. | Protons,electrons |
| As the motion of particles _ the particles move farther apart. | Increase |
| A _ is matter that has a definite shape and a definite volume. | Solid |
| The particles is a solid, simply _ back and forth in place. | Vibrate |
| A _ is 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 |
| _ is 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 Tention |
| A _ is 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 | Gas |
