Physic Question help #6

Lake Erie contains roughly 4.00 x 10^11 m^3 of water. (a) How much energy is required to raise the temperature of that volume of water from 11.4 degree C to 23.6 degree C? (Assume the density of this water to be equal to that of water at 20 degree C and 1 atm.) J (b) How many years would it take to supply this amount of energy by using the 1,200-MW exhaust energy of an electric power plant? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. yr

Explanation / Answer
