One mole of water is placed in surroundings at -3 °C, but at first it does not freeze (it remains as supercooled water). Suddenly it freezes. Calculate the entropy change in the system during the freezing, making use of the following data: CP„(water)=75.3JK'mol Cp„(ice)=37.7JK-mol¬ A,H(ice→water)=6.02kJ mol' at 0 °C The two Cp values can be assumed to be independent of temperature. Also, calculate the entropy change in the surroundings, and the net entropy change in the system and surroundings.
