change in entropy when watered converted to ice

1 kg of water at 20 degrees Celsius is converted into ice at -10 degrees Celsius. The heat capacity of water (at constant pressure) 4200(J/(kg degK) and that of ice is 2100J/(kg degK); the heat of fusion of ice at 0 deg. C is 3.36*10^5 J/kg.

a) what is the total change in entropy of the water-ice system.

b) If the density of water at 0 degC is taken as 10% than that of ice, what is the slope of the melting curve of ice at this temperature (give boyh magnitude and sign)

Solution Summary

It shows how to find the change in entropy when watered converted to ice. It also finds the slope of melting curve of ice. The solution is detailed and well presented.
