A heat pump is used to heat a home in the winter when the temperature in the ground is 0 °C and the temperature of the radiator in the house is 40 °C. When a Carnot cyclc is run backward for this purpose, the objective is to obtain as much heat in the radiator as possible for a given amount of electrical work. The coefficient of performance B' for a heat pump is define by: B' w| lg1|- |92| T1 T1 – T2 What is the minimum amount of electrical work needed to produce a kW-hour of heat?
