Calculate the change in entropy when exactly 1 mol of solid iodine, 12, at a temperature of 299. K is heated at constant pressure to produce liquid iodine at a temperature of 401. K. The constant pressure molar heat capacity of solid iodine is 54.44 J K-1 mol-1 and of liquid iodine is 80.67 J K-1 mol-¹. The melting temperature of iodine is 387 K, and the molar enthalpy of fusion of iodine is 7.87 kJ mol-1. ASM = JK-1 mol-1
