_______ 7. iPod g. chemical energy  thermal energy  mechanical energy
_______ 8. Speaker Vibrates h. nuclear energy  light energy and heat energy

Answer 1

1. Flashlight: a. chemical energy → electrical energy → light energy
2. Electric Saw: c. electrical energy → mechanical energy
3. Toaster: b. electrical energy → thermal energy
4. Gas-Powered Scooter: d. mechanical energy → electrical energy
5. The Sun: h. nuclear energy → light energy and heat energy
6. Wind Turbine: f. mechanical energy → electrical energy → sound energy
7. iPod: g. chemical energy → thermal energy → mechanical energy
8. Speaker Vibrates: e. mechanical energy → sound energy
