Question: A freezer with a coefficient of performance 30% that of a Carnot refrigerator keeps the inside temperature at -22C in a 25C room. 3.0 L

A freezer with a coefficient of performance 30% that of a Carnot refrigerator keeps the inside temperature at -22°C in a 25°C room. 3.0 L of water at 20°C are placed in the freezer. How long does it take for the water to freeze if the freezer’s compressor does work at the rate of 200 W while the water is freezing?
