Lake Erie contains roughly 4.00 multiplied by 1011 m3 of water.
(a) How much energy is required to raise the temperature of that volume of water from 11.0°C to 13.0°C?
(b) How many years would it take to supply this amount of energy by using the 950-MW exhaust energy of an electric power plant?
I will be happy to critique your thinking.
