Answer 1

Here are the correct matches for each situation with the corresponding energy transformation:

1. **Turning on a battery operated light**
**Match:** Electrical energy transformed into radiant energy

2. **A child going down a slide on a playground**
**Match:** Gravitational potential energy transformed into kinetic energy

3. **Using a gas power heater to warm a room**
**Match:** Chemical potential energy transformed into thermal energy

4. **Rubbing your hands together to warm them on a cold day**
**Match:** Kinetic energy being transformed into thermal energy

5. **Using a hand crank generator to produce electric current**
**Match:** Kinetic energy transformed into electric energy

6. **Using the light in your room that is plugged into the wall**
**Match:** Electrical energy transformed into radiant energy (Note: This would overlap with the first item but it's typically a different application of electrical energy.)

7. **A boy shooting a rubber band across the classroom**
**Match:** Elastic potential energy transformed into kinetic energy

8. **Using a dc electric motor**
**Match:** Electrical energy transformed into kinetic energy
