A heat pump is used to maintain a house at T1°C by extracting heat from the outside air on a day when the outside air temperature is T2°C. The house is estimated to lose heat at a rate of Q kJ/h, and the heat pump consumes 5 kW of electric power when running. Is this heat pump powerful enough to dothe job?
