The water at Niagara Falls drops through a height of 55.0 m. If the water’s loss of gravitational potential energy shows up as a
n increase in temperature of the water, what is the temperature difference between the water at the top of the falls and the water at the bottom? For this problem, if you need any of these values, use g = 10 m/s^2, take the specific heat of water to be 4000 J/(kg °C), and the latent heat of vaporization of water to be 2 × 10^6 J/kg.__________.
