| solid | the state in which matter has a definite shape and volume |
| liquid | the state in which matter takes the shape of its container and has a definite volume |
| gas | the state in which matter changes in both shape and volume |
| surface tension | the force on the particles at the surface of a liquid that causes the liquid to form spherical drops |
| viscosity | a liquid's resistance to flow |
| pressure | the amount of force exerted on a given area; expressed in pascals (Pa) |
| plasma | the state of matter that does not have definite shape or volume and whose particles have broken apart; plasma is composed of electrons and positively charged ions |
| freezing | the change of state from a liquid to a solid |
| melting | the change of state from a solid to a liquid |
| vaporization | the change of state from a liquid to a gas |
| condensation | the change of state from a gas to a liquid |
| sublimation | the change of state from a solid directly into a gas |
| buoyant force | the upward force on the object that is equal to the weight of the fluid that is displaced by the object |
| Pascal's Principle | states that force is transmitted equally in all directions throughout a fluid |
