| Three States of Matter | Solid, Liquid, and Gas |
| solid | the state of matter with a definite shape and volume |
| the particles are close together and vibrate in place | solid |
| liquid | the state of matter that has a definite volume but not a definite shape |
| These particles are close together but can slide past each other | liquid |
| gas | the state of matter with no definite shape or volume |
| temperature | the measure of how fast the particles in an object are moving |
| Boyle's Law | the volume of a gas is inversely proportional to the pressure of a gas when temperature if constant |
| Charles's Law | the voume of a gas is directly proportional to the temperature of a gas when pressure is constant |
| relationship of volume and pressure in gases | Boyle's Law |
| relationship of temperature and volume | Charles's Law |
| Change of State | the change of a substance from one physical form to another |
| melting | solid becomes a liquid |
| freezing | liquid becomes a solid |
| 0 degrees | temperature that ice melts and freezes |
| boiling points and freezing points | are physical properties |
| boiling | the change of a liquid to a vapor, or gas |
| 100 degrees | boiling point |
| evaporation | change from liquid to gas, opposite of condensation |
| condensation | change from gas to liquid, opposite of evaporation |
| sublimation | change of state from solid to gas |
| particles are far apart , move very fast, & break away | gas |
| exothermic | energy is removed (freezing) |
| endothermic | energy is gained (melting) |
| at high temperatures | particle in an object move faster |
| a heated balloon expands | Example of Charle's Law |
| atmospheric pressure | lowers the boiling point of water |
| can happen at any temperature | EVAPORATION |
| pressure | the amount of force exerted on an object |
| viscosity | a liquids resistance to flow |
| temperature | a measure of how fast the particles are moving |
