| states of matter | solid, liquid, gas, and plasma |
| kinetic theory of matter | tiny particles in constant motion make up all matter |
| crystal | particles are arranged in repeating geometric patterns |
| plasma | gaslike mixture of positively and negatively charged particles |
| thermal expansion | matter expands when heated and contracts when cooled |
| evaporation | liquid gradually changes to a gas |
| condensation | gas changes to a liquid |
| heat of fusion | amount of energy needed to change a material from a solid to a liquid |
| heat of vaporization | amount of energy needed to change a material from a liquid to a gas |
| pressure | amount of force exerted per unit area |
| pascal | SI unit of pressure |
| Boyle's Law | decrease volume, increase pressure of a gas |
| Charles's Law | temperature increases, volume of a gas increases |
