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

Options

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

Answer

B

Explanation

In a hydro-electric power plant, more electrical power can be generated if water falls from a greater height because water at greater height has more potential energy. When it falls it will have greater kinetic energy associated with it. A larger amount of potential energy is converted into kinetic energy due to which more electric power will be obtained.
