Answer:
The temperature rise of the water is = 0.14 °c
Explanation:
Height = 60 m
Potential energy change ΔP =
ΔP = m × 9.81 × 60
ΔP = (588.6 × m) Joule
Since the Potential energy change is equal to the internal energy change or Enthalpy change.
ΔP = ΔH
Since ΔH = m × C × ΔT
⇒ ΔP = m × C × ΔT
Put all the values in above formula we get
⇒ 588.6 × m = m × 4184 × ΔT
⇒ ΔT= 0.14 °c
Therefore the temperature rise of the water is = 0.14 °c
