Entropy - Help! Water --> Ice
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
I know delta S_universe = delta S_system + delta S_surroundings, but i am a little stuck, any pointers?

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?
