a freezer with a coefficient of performance of 3.88 is used to convert 1.75 kg of water to ice in one hour. The water starts at a temperature of 20.0 degrees celcius, and the ice that is produced is cooled to a temperature of -5.00 degrees celcius.
(a) how much heat must be removed from the water for this process to occur?
(b) how much electrical energy does the freezer use during this hour of operation?
(c) how much heat is discarded into the room that houses the freezer?
