Water falls from a height 500 m. The rise in temperature of water at bottom if whole of the energy remains in water, will be: (specific heat of water is 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Potential energy 
increase in heat of water.
From law of conservation of energy, we know that energy can neither be created nor destroyed, it remains conserved. When water falls from a height, it has potential energy 
, this is used in heating up the water 
.
Hence, we have
