Solution

Q.
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 $m / s^{2}$ specific heat of water = 4200 J/(kg K)) [2025]

1 0.23 K

2 0.36 K

3 0.14 K

4 0.48 K

Ans.
(4)

$m g h = m s △ T$

$\Rightarrow △ T = \frac{g h}{s} = \frac{10 \times 200}{4200} = 0.48 K$
