1. Chemical potential energy -> Electrical energy -> Kinetic + heat + sound energy

2. Elastic potential energy -> Kinetic + heat + sound energy

3. Chemical potential energy -> Electrical energy -> Light + heat energy

4. Chemical energy -> Kinetic + heat + sound energy

4.2

describe energy transfers involving the following forms of energy:
thermal (heat), light, electrical, sound, kinetic, chemical, nuclear and potential (elastic and gravitational)

Extension: What does "potential" mean?
Stored energy
