A “Carnot” refrigerator (the reverse of a Carnot engine)absorbs heat from the freezer compartment at a temperatureof –17°C and exhausts it into the room at 25°C. (a) Howmuch work would the refrigerator do to change 0.65 kg of waterat 25°C into ice at –17°C (b) If the compressor output is105 W and runs 25% of the time, how long will this take?
