A refrigerator is driven by `1000 W` electric motor having an efficiency of `60%`. The refrigerator is considerd as a reversible heat engine operating between `273K and 303K`. Calculate the time required by it to freeze `32.5 kg` of water at `0^(@)C`. Heat losses may be rejected. Latent heat of fusion of ice `= 336xx10^(3)J kg^(-1)`.
