A waterfall is 70 m high.What is the increase in water temperature at the bottom of the falls if all the initial potential energy goes into heating the water? (g = 9.8 m/s²,c_w = 4186 J/kg·°C) A) 0.16°C B) 0.34°C C) 0.69°C D) 1.04°C

Question

The potential energy converted to heat is mgh = mcΔT. Solving for ΔT gives ΔT = gh/c. Substituting the given values: ΔT = (9.8 m/s² * 70 m) / 4186 J/kg·°C = 0.16°C.
