Question

A battery powers a circuit for a small noisy fan. The fan's motor gets warm as it turns. What energy transformations are

Answer 1

Answer:

Electric potential energy in the battery transforms to electric energy. Electric energy transforms to motion energy (spinning fan blades), sound energy (noise), and thermal energy (a warm motor).

Answer 2

Answer:

Chemical energy to electrical energy to mechanical and thermal energy

Explanation:

In the rotating fan, the chemical energy stored in the battery is used to generate electrical energy.

The electrolytes within the battery undergoes chemical reactions that produces electric current.

• The current is being used to drive the motor of the fan to produce a mechanical energy as it rotates.
• In like manner, heat energy is also produced.
• So, energy is simply being transformed from one form to the other in this system.
