Water fall from a height 50m, If one third of its mechanical energy converted into heat what will be the rise in temperature of water

In a water-fall the water falls from a height of 100 m . If the entire K.E. of water is converted into heat, the rise in temperature of water will be

Water falls on the ground from 42 m height. It half of loss is potential energy converts into heat, then increase in temperature of water is

In the experiment to study the effect of heat on ice, what will be the maximum rise in temperature of water?

Water drops from a height of 40 m in a waterfall. if 75% of its energy is converted into heat and absorbed by the water, the rise in temperature of the water will be

A water fall is 84 m high. Assuming that half the kinetic energy of falling water get converted to heat, the rise in temperature of water is
