Question

Water fall at Narora dam from 200 m height. If during fall whole energy converts into heat and it is absorbed by falling water, then calculate increase in temperature.

Answer 1

h = 200 m

If mkg water falls on the earth, then absorbed heat by water.

Q = m g h J

If temperature increase is ∆θ, then

Q = mS ∆θ

∴ mS ∆θ = mgh

 

Based on thermal conduction and thermal current
