Here is my question:

10 kg of h2o at 20 degrees C is converted to Ice at -10 degrees C by being put in contact with a reservoir at -10 degrees C. The process takes place at constant pressure. The heat capacities at constant pressure of water (Cp_h2o) and Ice (Cp_ice) are

4180 and 2190 (J)/(kg)*(K) respectively. The heat of fusion of water, l_h2o, is

3.35x10^5 (J)/(kg).Calculate the change in entropy of the universe.

I know delta S_universe = delta S_system + delta S_surroundings, but i am a little stuck, any pointers? :yuck:
