A freezer has a coefficient of performance equal to 4.0. How much electrical energy must this freezer use to produce 1.5 kg of ice at −5.0 °C from water at 15 °C?
Step 1 of 3
Here, we have to find out the electrical energy needed to freeze the water to the ice.
The coefficient of performance of the refrigerator,
Where, - Heat energy taken from the cold reservoir
- Work done as input
