Question

A waterfall is 1.260m high. Calculate the change in temperature of a quantity of water that falls from the top to the bottom of the waterfall. (Neglect heat losses to the surroundings, take g as 10m-2 and specific heat capacity of water as 4200Jkg-1K-1)

Options

A) 0.3°C

B) 3.0°C

C) 33.3°C

D) 42.0°C

E) 100.0°C


The correct answer is B.

Explanation:

\(\Delta t = \frac{gh}{c} = \frac{1260 \times 10}{4200}\)
= 3.0°C
