Question

In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because:

• A. more water molecules dissociate into ions
• B. its temperature increases
• C. larger amount of potential energy is converted into kinetic energy
• D. the electricity content of water increases with height

Answer 1

The correct option is C

larger amount of potential energy is converted into kinetic energy

In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because greater height means larger potential energy, and this larger amount of potential energy is converted into larger kinetic energy.
