Detailed Solution

The above statement is False.
The type of energy in the water that is stored in a dam is Potential energy.
The water held behind the dam has potential energy because of its position water in the reservoir is on height, and when something is at a certain height, it possesses potential energy.
The water that is deposited beyond the dam has potential energy. This is because of the water position that is stored in the dam. Some of the water is permitted to pass along a tunnel, which is present in the dam. The potential energy in the stored water changes into kinetic energy when the water moves through the tunnel.
Therefore, as the water stored in a dam's reservoir flows out, its potential energy changes to kinetic energy.
Therefore the correct statement would be that the energy possessed by water stored in a dam is Potential energy.
