a heat pump is set to keep a room at 17°c by moving heat from outside to inside. heat naturally leaves the room (e.g. through windows/walls etc.) at a rate of 1800 j/s. the cop of the heat pump is 6, and it draws 900w while it is running. a) what fraction of each hour must the heat pump be running? b) if electricity costs $0.07/kw h, how much will the heat pump cost each month (30 days)?
