Question

(B) When water is at a certain height,it possesses gravitational potential energy.As the water falls,this gravitational potential energy is converted

Vedclass · Accepted Answer

Due to the conversion of gravitational potential energy into kinetic energy and then into heat energy.

Vedclass · Answer

(B) When water is at a certain height,it possesses gravitational potential energy.As the water falls,this gravitational potential energy is converted into kinetic energy.Upon reaching the bottom,the water molecules collide with each other and with the rocks,causing this kinetic energy to dissipate as heat energy.Consequently,the water at the bottom of the waterfall is warmer than the water at the top.

Why is the water at the bottom of a waterfall warmer than the water at the top?
