Two Carnot air conditioners, A and B, are removing heat from different rooms. The outside temperature is the same for both rooms, 315 K. The room serviced by unit A is kept at a temperature of 295 K, while the room serviced by unit B is kept at 298 K. The heat removed from either room is 4550 J. For both units, find (a), (b) the magnitude of the work required and (c), (d) the magnitude of the heat deposited outside for A and B conditioners respectively.
