| A | B |
|---|
| Solid | vibrates in place, fixed volume/shape, particles cannot change neighbors, low energy high attraction |
| Liquid | Particles flow around each other, medium energy but still too attracted to separate, fixed volume not shape |
| Gas | Particles have overcome all attraction with high energy, no fixed vol/shape, can be compressed with pressure |
| Endothermic | change taking in heat (melting, vaporization) |
| Exothermic | change giving off heat (condensation, freezing) |
| Vaporization | Going from liquid to gas (boiling OR evaporation) |
| Boiling | all liquid at a temperature that can move it to a gaseous state |
| Evaporating | liquid particles at the top gain energy to move to a gaseous state |
| Condensation | from a gas to a liquid, what happens on the outside of ice tea glasses in the summer |
| Melting | from a solid to a liquid, endothermic change into a liquid |
| Freezing | going from a liquid to a solid, exothermic change into a solid |
| Subliming | From a solid to a gas directly |
| Density definition | how closely packed together and how heavy the particles are in a substance |
| Density Equation | Mass / volume |
| Buoyant Force | Force equal to the amount of liquid displaced |
