A heat pump is under consideration for heating a research station located on an Antarctica ice shelf. The interior of the station is to be kept at 158C. Determine the maximum theoretical rate of heating provided by a heat pump, in kW per kW of power input, in each of two cases: The role of the cold reservoir is played by (a) the atmosphere at 2208C, (b) ocean water at 58C
