2. Changes between solid and liquid
Melting
Solid to a liquid
Requires an input of energy
At the melting point, solid particles get enough energy to break free from one another.

3. Changes between solid and liquid
Freezing
Liquid to solid
Requires a loss of energy
At the freezing point, the liquid particles slow down and start to form tight arrangements.

4. Changes between liquid and gas
Vaporization
Liquid to a gas
Requires an input of energy

5. Changes between liquid and gas
Vaporization
Two types:
Evaporation =
vaporization on the surface only
Boiling =
Vaporization throughout the entire liquid
At the boiling point, liquid particles get enough energy to escape as a gas.

6. Changes between liquid and gas
Condensation
Gas to a liquid
Requires a loss of energy
The gas particles slow down and start getting closer together.

7. Changes between solid and gas
Sublimation
Solid directly to a gas
Requires an input of energy

8. Changes between solid and gas
Deposition
Gas directly to a solid
Requires an loss of energy
