JEE Main 2025 Physics question
Water falls from a height of 200 m into a pool. Calculate the rise in temperature of the water assuming no heat dissipation from the water in the pool.
(Take g = 10 m/s, specific heat of water = 4200 J/(kgK))
Answer: (3)
Solution
mgh = msΔT, ΔT = gh/S = (10×200)/4200 = 0.48 K.
