Question

The temperature of water at the bottom of a large waterfall is higher than that of the water at the top, because

• A. the falling water absorbs heat from the sun
• B. the KE of the falling water is converted into heat
• C. the water at the bottom has greater PE
• D. rocks on the bed of the river give out heat

Answer 1

The correct option is B the KE of the falling water is converted into heat

It is because of the reason that the kinetic energy of the falling water is converted into heat due to the friction acting between the water and the ground.
