Mixing Hot and Cool Water
LEARNING TARGET: I will investigate what happens to thermal energy between water samples of different volumes and temperatures.
CH Q
What happens to the energy when hot and cool water are mixed?
VOCAB: next slide

3. Review: conduction – Insulation – Heat – Temperature -
transfer of heat through touching
prevents movement of thermal energy
process of transferring thermal energy
measure of particle movement

4. PROCEDURE AND DATA
MATERIALS:
PROCEDURE: Read on pg. D and summarize
DATA: WS Mixing Water Data

5. SUGGESTED RESULTS

6. Do your results support the Law of Conservation of Energy? Explain.
POST DISCUSSION
Do your results support the Law of Conservation of Energy? Explain.
Do your results support the idea that thermal energy is transferred from hot to cold and not the other way around? Explain.
YES. However a little energy was lost to environment, no new thermal energy appeared.
YES.
If there's more hot water there is more energy. Equal amounts ended up ½ way.

7. 3. In this experiment, how does the process of heating compare to how energy moves in a home?
Styrofoam cup like walls/insulation.
Surface (where a lot of heat lost to environment) is like windows/leaks.

8. ANALYSIS
- Discuss and answer Q 2-4 & 6 on pg.D 49
ANS CH Q
What happens to the energy when hot and cool water are mixed? A:
thermal energy moves from HOT TO COLD
