When liquid water at 0°C and 1 atm is converted to ice at 0°C and 1 atm, 6.01 kJ mol-1 of energy is released as heat to the surroundings. Calculate the change of entropy for the water, ΔSwater , and for the surroundings, ΔSsur , when 1.00 mole of water freezes at 0°C and the surroundings are at (a) 0°C, (b) -2°C. Explain the physical origin of the difference.
