A 74.6-g ice cube fl oats in the Arctic Sea. The temperature and pressure of the system and surroundings are at 1 atm and 0°C. Calculate ∆Ssys, ∆Ssurr, and ∆Suniv for the melting of the ice cube. What can you conclude about the nature of the process from the value of ∆Suniv? (The molar heat of fusion of water is 6.01 kJ/mol.)
