(a) How much work must a Carnet refrigerator do on a hot day to transfer 1000 J of heat from its interior at l0°C to the outside air at 35.0°C?
(b) How much work must the same refrigerator do to transfer the same amount of heat if the interior temperature is the same, but the outside air is at only 15.0°C?
(c) Sketch pV diagrams for these two situations. Can you explain in physical terms why more work must be done when the temperature difference between the two isothermal stages is greater?
