| matter | anything that takes up space and has mass |
| solid | matter w/a definite shape |
| liquid | definite volume, but no definite shape |
| viscosity | a liquid's resistance flow (example honey) |
| surface tension | causes liquid to act as if a thin film were stretched across the surface |
| gas | matter that does not have a definite shape or volume |
| thermal energy | extensive property, depends on the number of particles in a substance as well as the amount of energy each particle has |
| temperature | average kinetic energy |
| heat | the movement of thermal energy from a substance at a higher temperature to one at a lower temperature |
| melting | change from a solid state to a liquid state |
| freezing | change from a liquid state to a solid state |
| vaporization | change from a liquid to a gas |
| condensation | change from a gas to a liquid |
| pressure | equal to the force exerted on a surface divided by the total area over which the force is exerted (pressure = force/area |
| buoyant force | upward force on an object immersed in fluid |
| Archimedes' principle | the buoyant force on an object is equal to the weight of the fluid displaced by the object |
| density | density is mass divided by volume (density = mass/volume |
| Pascal's principle | When a force is applied to a confined fluid an increase in pressure is transmitted equally to all parts of the fluid |
