Energy Transformations
Choose the sequence of energy forms that best fits each item.
1. Flashlight a. chemical energy→ electrical energy→ light energy
2. Electric saw b. electrical energy → thermal energy
3. Toaster c. electrical energy → mechanical energy
4. Gas Scooter d. mechanical energy → electrical energy
5. The Sun e. mechanical energy → sound energy
6. Wind Turbine f. chemical energy → electrical energy →sound energy
7. iPod g. chemical energy → thermal energy →mechanical energy
8. Speaker vibrates h. nuclear energy → light energy and heat energy
(9) energy from gas, oil, or coal provides
(10) energy to produce steam. A turbine changes the energy of the steam into the
(11) energy of the rotating turbine and generator. The generator converts this energy into
(12) energy. The lamp is an energy converter, changing (13) energy to
(14) energy.
