A refrigerator is characterized by a number called the coefficient of performance

A refrigerator is characterized by a number called the coefficient of performance (COP), which is defined as the heat removed from the cool place (inside the fridge) divided by the work required to remove that heat: COP = QL/W. (a) If you are buying a new fridge is it better to buy one with a higher COP or a lower COP? O higher lower O it doesn't matter Let's say that a fridge operates between temperatures of 4C and 27.0C. A particular fridge has a COP of 4.30. (b) If 460 of work is done by the compressor in the fridge to extract heat from inside the fridge, how much heat is removed from inside the fridge? J (c) How much heat is dumped by the fridge into the surroundings, in this case? (d) What is the maximum possible COP that would be achieved by an ideal fridge operating between the two temperatures specified above?
