Reference no: EM13553107

A freezer has a coefficient of performance of 2.52 . The freezer is to convert 1.90 kg of water at 26.0 Celsius 1.90 kg of ice at -5.00 Celsius in 1 hour.

1) What amount of heat must be removed from the water at 26.0 Celsius to convert it to ice at -5.00 Celsius?

2) How much electrical energy is consumed by the freezer during this hour?

3) How much wasted heat is rejected to the room in which the freezer sits?
