(a) A freezer maintains an interior temperature inside of -22.0°C and has a coefficient of performance of 3.00. The freezer sits in a room with a temperature of 22.0°C. The freezer is able to completely convert 20.0 g of liquid water at 22.0°C to ice at -22.0°C in one minute. What input power (in watts) does the freezer require? (The specific heat of liquid water is 4.186 J/(g. °C), the specific heat of ice is 2.090 J/(g· °C), and the latent heat of fusion of water is 334 J/g.) W (b) What If? In reality, only part of the power consumption of a freezer is used to make ice. The remainder is used to maintain the temperature of the rest of the freezer. Suppose, however, that 100% of a freezer's typical power consumption of 160 W is available to make ice. The freezer has the same coefficient of performance as given above. How many grams per minute of water at 22.0°C could this freezer convert to ice at -22.0°C? g/min
