JEE Main 2025 Physics question

PhysicsWork, Energy and PowerJEE Main 2025

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.
