2. Phase changes Solid to liquid -> Liquid to gas
Energy is absorbed
Gas to liquid-> Liquid to solid
Energy is released

3. Example of Phase Change

4. Energy Flow Hot to Cold High energy to Low energy
Caused by nature trying to get everything to the same temperature

5. Question 1 When a liquid gains energy does it become a solid or a gas?

6. Question 2
When thermal energy is absorbed what are the phase changes that occur?
Solid to Liquid and Liquid to gas

7. Question 3
Fill out the chart
Liquid
Solid
Gas

8. Question 4 Does energy flow from hot to cold or cold to hot?

9. Question 5 What causes energy flow?
Nature trying to balance temperature.
