|---|
| state of matter | physical form; solid, liquid, gas |
| solid | particles move in place; volume and shape are fixed |
| liquid | particles slide past one another; definite volume but not a definite shape |
| surface tension | force of attraction at the surface of a liquid holding particles together |
| viscosity | resistance to flow |
| gas | no definite volume or shape; particles move fast past each other |
| temperature | measurement of the movement of particles (kinetic energy) |
| volume | amount of 3-d space taken up |
| pressure | amount of force exerted on a surface |
| Boyle's Law | all about pressure (increased pressure=decreased volume) (decreased pressure= increased volume of a gas) |
| Charles' Law | all about temperature and gases (increased temperature= increased volume) (decreased temperature=decreased volume) |
| change of state | change of physical state |
| melting | add energy=solid to liquid |
| evaporation | add energy= liquid to gas (at surface) |
| boiling | add energy= liquid to gas (throughout substance) |
| condensation | take away energy=gas to liquid |
| sublimation | add energy=solid directly to gas |
