A Carnot freezer that runs on electricity removes heat from the freezer compartment, which is at -10.0C and expels it into the room at 27.0C. You put an ice-cube tray containing 360gof water at 18.0C into the freezer. What is the coefficient of performance of this freezer? How much energy is needed to freeze the water?How much electrical energy must be supplied to the freezer to freeze the water?How much heat does the freezer expel into the room while freezing the ice?
