Question

In the process: H_2O(s,-10°C,1 atm) H_2O(l,10°C,1 atm). C_P for ice =9 cal deg^ -1 mol^ -1 , C_P for H_2O(l)=18 cal deg^ -1 mol^ -1 . Latent heat of fusion of ice =1440 cal mol^ -1 at 0°C. The entropy change for the above process is 6.258 cal deg^ -1 mol^ -1 . Give the total number of steps (among heating the ice, melting the ice, and heating the water) in which the third law of thermodynamics is used.
