Question

(a) A freezer maintains an interior temperature inside of -22.0°C and has a coefficient of performance of 3.00. The freezer sits a room with a temperature of 25.0°C. The freezer is able to etely canvert 090 J/(9 °C), and the latent heat of & one minute. What input power (in watts) does the freezer require? (The specific heat of liquid water is 4.186 J/(g °C), liquid water at 25.0-tolce specific he ice is of water is 33 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 is available to make ice. The freezer has the same coefficient of performance as given above. How many grams per minute of water at 25.0°C could this freezer convert to ice at -22.0°C? 62 How is power related to work and time? How is the work related to the COP and the energy extracted from the ice, 1Q.1? Note the energy extracted per unit mase is the same as in part m units of grams per minute. g/min (a).
