Imagine a Carnot heat pump operates between an outside temperature of 0 °C and an inside temperature of 20.0 °C . What is the work needed if the heat delivered to the inside of the house is 30.0 kJ?StrategyBecause the heat pump is assumed to be a Carnot pump, its performance coefficient is given by KP = Qh /W = Th /(Th − Tc). Thus, we can find the work W from the heat delivered Qh.
