GR.8 Chap. 8 States of Matter
| Question | Answer |
|---|---|
| gas | matter with no definite volume or shape |
| liquid | matter with definite volume but no definite shape |
| matter | anything that has mass and takes up space |
| solid | matter with a definite volume and shape |
| surface tension | uneven forces acting on the particles on the surface of a liquid |
| vapor | gas state of a substance that is normally a solid or liquid at room temperature |
| viscosity | measurement of a liquid's resistance to flow |
| condensation | change of state from a gas to a liquid |
| deposition | change of state of a gas to a solid without going through the liquid state |
| evaporation | vaporization that occurs only at the surface of a liquid |
| kinetic energy | kind of energy that an object has due to its motion |
| sublimation | change of state of a solid to a gas without going through the liquid state |
| temperature | measure of the average kinetic energy of all of the particles in an object |
| thermal energy | total potential and kinetic energies of an object |
| vaporization | change of state of a liquid to a gas |
| Boyles Law | states that the pressure of a gas increases if the volume decreases and pressure of a gas decreases if volume increases when temperature is constant |
| Charles Law | states that the volume of a gas increases with increasing temperature if the pressure is constant |
| kinetic molecular theory | how particles in matter behave |
| pressure | amount of force applied per unit of area |
