Lake erie contains roughly 4.00 ✕ 1011 m3 of water. (a) how much energy is required to raise the temperature of that volume of water from 17.8°c to 21.6°c? (assume the density of this water to be equal to that of water at 20°c and 1 atm.) j (b) how many years would it take to supply this amount of energy by using the 1,400-mw exhaust energy of an electric power plant? yr
