A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 21°C. The exterior air, which is at 10°C, serves as the source. Calculate the rate of entropy change of the two reservoirs and determine if this heat pump satisfies the second law according to the increase of entropy principle.
