Question

How does a hydroelectric power plant convert energy?

Answer 1

Answer: edge 2020

A number of energy transformations occur when water that is stored behind a dam is changed into electrical energy. For each step listed, identify the energy transformation.

Lake water flows downward through tunnels.

✔ potential to kinetic

Flowing water turns turbines.

✔ kinetic to mechanical

Turbines generate electricity.

✔ mechanical to electrical

Explanation:

Answer 2

Answer:

D. As water flows through the channels toward the turbines, it has kinetic energy. This is changed to mechanical energy as the water turns the turbines. Then the mechanical energy of the turbines is changed to electrical energy by the generator.
