A water fall is 420m high. Calculate the difference in temperature of the water between the top and bottom of the water fall. Neglect heat loses(g = 10.0m-2 specific heat capacity of water = 4.20 x 103 JKg-1 K-1)
0.1oC
1.0oC
42oC
100oC
4.20oC
Correct answer is B
Potential Energy = Heat Energy
mgh = McΔθ=ghc=10×2404.20×103
= 1.0oC
