Question
A freezer has a coefficient of performance of 6.30. It is advertised as using 436 kWh/yr. Note: One kilowatt-hour (kWh) is an amount of energy equal to running a 1-kW appliance for one hour.
Energy used in a single day - 4360000 J
Energy removed from fridge in a single day - 27468000
(c) What maximum mass of water at 22.5°C could the freezer freeze in a single day (in kg)? (The latent heat of fusion of water is 3.33 105 J/kg, and its specific heat is 4186 J/kg · °C.)
