A Carnot freezer that runs on electricity removes heat from the freezer compartment, which is at -10.0 °C and expels it into the room at 25.0 °C. You put an ice-cube tray containing 390 g of water at 16.0 °C into the freezer.

a-What is the coefficient of performance of this freezer?

b-How much energy is needed to freeze this water?

c-How much electrical energy must be supplied to the freezer to freeze the water?

d-How much heat does the freezer expel into the room while freezing the ice?
