| A | B |
| Matter | Anythintg that has mass and takes up space |
| Melting | Solid to a liquid |
| Boiling | Lipuid to gas from bottom of a liquid |
| Evaporation | Liquid to gas from surface of the liquid |
| Sublimation | Solid changing directly to a gas |
| Freezing | Liquid to a solid by reaching frreezig. |
| Condensation | Gas to a liquid. |
| Solid | Particles are tightly packed and have a defenite shape and volume. |
| Liquid | Particles move fast enough to overcome most attraction and can slide past each other. |
| Gas | no defenite shape or volume |
| Boyle's Law | the volume of a gas is inversely proportional with the pressure of a gas. |
| Charles' Law | When pressure is constant volume of a gas is directly proportional to the temperature of a gas. |
