In a hydroelectric power plant more electrical power can be generated if water falls a greater height because :
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
Text Solution
Verified by Experts
The correct Answer is:
B
In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because the rise in water level, causes the increase in potential energy of water. Thus when it flows from higher position more amount of kinetic energy is formed by the conversion of higher potential energy and this kinetic energy in the form of moving water can produce more electrical power.
