4. [25] One mole of water is placed in surroundings at 3C, but at first it does not freeze (it remains as supercooled water). Suddenly it freezes. Heat capacities and enthalpy change are given below. Cp,m(water)=75.3J/molKCp,m(ice)=37.7J/molKfusH(icewater)=6.02kJ/molat0C (1) Calculate the entropy change in the system during the freezing, assuming the two Cp values are independent of temperature. (2) Calculate the entropy change in the surroundings and the net (total) entropy change in the system and surroundings. (3) Is the process spontaneous? Why
