CBSE Class 11-science Answered

Explain why the water at the foot of the waterfall is at different temperature from that at the top?

Asked by Topperlearning User | 08 Jul, 2014, 10:34: AM
Expert Answer

When water reaches the ground, its gravitational potential energy is converted into kinetic energy. A part of its kinetic energy is converted into heat on reaching the surface. This causes a rise in temperature of water. So, the water at the foot of the waterfall is at a higher temperature as compared to the water at the top of the waterfall.
