Question

We said in section 8.1 that the potential energy of water at the top of a dam or waterfall is converted into heat when the water dashes against rocks at the bottom. the potential energy of the water at the top is equal to Ep=mgh, where m is the mass of the water, gi s the acceleration of the falling water due to gravity (g=9.81 m/s^2) and h is the height of the water. ASsuming that all the energy is converted to heat, calculate the temperature rise of the water in degrrees Celsius after falling over California's yosemite falls, a distance of 739m. The specific hea t of water is 4.18 J/g*K)

Explanation / Answer
