Randall D. Knight β Heat Engines and Refrigerators: Problem 42
A freezer with a coefficient of performance 30% that of a Carnot refrigerator keeps the inside temperature at $-22^{\circ}\text{C}$ in a $25^{\circ}\text{C}$ room. $3.0\text{ L}$ of water at $20^{\circ}\text{C}$ are placed in the freezer. How long does it take for the water to freeze if the freezerβs compressor does work at the rate of $200\text{ W}$ while the water is freezing?
