Chapter 12.2, Problem 34SSC

To determine

To Explain: The reason J J expected a temperature difference between top and bottom of the waterfall.

Explanation of Solution

Introduction:

Energy transformation is the conversion of energy from one form to another.

Water at a height will have potential energy. On falling down, the potential energy will convert into kinetic energy. On striking the ground, the kinetic energy will convert into heat and other forms of energy. Such heat will raise the temperature of the water as expected by J J.

Conclusion:

The potential energy in the water converts to heat energy thereby raising the temperature of water.
