A waterfall is 1 260m high Calculate the change... - WAEC Physics 1998 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)
A
0.3oC
B
3.0oC
C
33.3oC
D
42.0oC
correct option: b
\(\Delta t = \frac{gh}{c} = \frac{1260 \times 10}{4200}\)
= 3.0o
= 3.0o
