A litre of water at 20∘C is placed in a fridge at 5∘C. Calculate the change in entropy of the water in J/K, (including the sign), once all the water has come into thermal equilibrium and calculate the change in entropy of the fridge in J/K, (including the sign). Note: the specific heat of water is cp = 4190 J/(K kg).
