Second law of thermodynamics refrigerator

1. A heat pump uses 300 J of work to remove 400 J of heat from the low-temperature reservoir. How much heat is delivered to a higher temperature reservoir? Solution: W = 300 J QC = 400 J QH = W + QC QH = 300 J + 400 J QH =700 J Heat delivered to the higher temperature reservoir is 700 J. 2.
