A 74.6-g ice cube floats in the Arctic Sea. The temperature and pressure of the system and surroundings are at 1 atm and 0 degrees C. Calculate delta S(sys), delta S (surr), and delta S (univ) for the melting of the ice cube. What can you conclude about the nature of the process from the value of delta S (univ)? (The molar heat of fusion of water is 6.01 KJ/mol.)
