Types of Energy and Conservation of Energy

What energy transformations take place when a battery-operated radio is in use?

• Electrical to chemical to radiant

• Sound to chemical to mechanical

• Chemical to electrical to sound

• Radiant to electrical to thermal

The picture shows a microwave oven. As a microwave oven is operated, electrical energy is transformed into all of the following types of energy EXCEPT —

• solar

• light

• thermal

• mechanical
