1. The problem statement, all variables and given/known data A freezer has a coefficient of performance of 6.30. It is advertised as using electricity at a rate of 457kWh/yr. a)On average how much energy does it use in a single day? b) What maximum mass of water at 20.0 degree celsius could the freezer freeze in a single day. NOTE: One kilowatt hour is an amount of energy equal to running a 1-kW appliance for one hour 2. Relevant equations COP = Q / W 3. The attempt at a solution I tried to use comparison like so; if 457kWh is the rate for 365 days then xkWh is the rate for 1 day This gives me 1.25 J which is very wrong. Please can i get clues on how to start or what to do on the "A" part of the question. It's really twisting my head..thanks a lot for your help..
