A 77.4 g ice cube floats in the Artic Sea. The temperature and pressure of the system and surroundings are at 1 atm and 0C.Calculate ΔSsys, ΔSsurr,ΔSuniv, for the melting of the ice cube. (The molarheat of fusion of water is 6.01 kJ/mol.)What can you conclude about the nature of the process from the value of ΔSuniv?A) The system is not an equilibrium processB) The system is an equilibrium process
