A refrigerator converts 1.3 kg of water at `20^(@)C` into ice at `-15^(@)C` in 1 hour. Calculate the effective power of the refrigerator. Specific latent heat of fusion of ice `= 3.4 xx 10^(5) J kg^(-1)` Specific heat capacity of water `= 4.2 xx 10^(3) J kg^(-1) K^(-1)` Specific heat capacity of ice `= 2.1 xx 10^(3) J kg^(-1) K^(-1)`
