Question on: WAEC Physics - 1998
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)
A
0.3oC
B
3.0oC
C
33.3oC
D
42.0oC
Ask EduPadi AI for a detailed answer
Correct Option: B
(\Delta t = \frac{gh}{c} = \frac{1260 \times 10}{4200})
= 3.0o
