Question

Will water at the foot of the waterfall be at a different temperature from that at the top? If yes, explain.

Answer 1

Yes,water is slightly warmer at the bottom of a waterfall than at the top because the gravitational potential energy is converted first to kinetic energy of the falling water, and finally to heat energy as it comes to rest at the bottom. 
hope this helps friend !

Answer 2

Answer:

Yes, the water at the foot of the waterfall will be at a different temperature from that at the top.

Explanation:

During the descent, the energy stored in the water at the top is turned into heat energy. During its descent, the water receives Kinetic energy and loses potential energy.

Kinetic energy is the energy that an item or particle has as a result of its movement. When work is done on an object by exerting a net force, the object accelerates and gains kinetic energy as a result.

Potential energy is the energy that is stored in a system and is determined by the relative positions of various pieces of the system.

Thus, the water temperature will be always different at the foot as compared with the temperature at the top.
