The latest heat of fusion of a material is 6 kJ/mol and the heat capacity (Cp ) in solid and liquid phases of the material is a linear function of temperature Cp = 30.6 + 0.0103 T , with units J/mol/K. How much heat is required to increase the temperature of 1 mol of the material from 20 to 200°C if the fusion phase transition occurs at 80°C?

Solution:
The latest heat of fusion of a material is 6 kJ/mol and the heat capacity (Cp )
