The upper falls in Yosemite National park, at 440 m, is among the 20 highest waterfalls in the world. Estimate the difference between the temperature of the water at the top and bottom of the falls. The molar heat capacity of water (molecular mass 0.018 kg) is 80 J K-1 . The acceleration due to gravity is 9.8 Neglect evaporation and the change in elevation.
