A freezer has a coefficient of performance (COP) of 6.30 and is advertised as using 466 kWh per year.
Note: One kilowatt-hour (kWh) represents the amount of energy consumed by a 1-kW appliance operating for one hour.
(a) On average, how much energy does the freezer consume in a single day? Please provide your answer in joules (J).
(b) On average, how much energy does the freezer remove from the refrigerator in a single day? Please provide your answer in joules (J).
(c) What is the maximum mass of water at 17.1°C that the freezer could freeze in a single day? (The latent heat of fusion of water is 3.33 x 10^5 J/kg, and its specific heat is 4186 J/kg·°C.) Please provide your answer in kilograms (kg).
