Coefficient of Performance, COP:

QC is the heat removed from inside and W is the work done. The two must be equal for the coefficient of performance to be 1.

QH is the heat supplied by the hot reservoir/outside. TC is the temperature of the cold body and TH is the temperature of the hot body. ###### Problem Details
