Interpretation:
The molar heat vaporization of liquid iodine has to be calculated.
Concept Introduction:
The molar heat of vaporization, fusion and sublimation means the heat energy absorbed or released when 1 mole of a substance changes its phase by vaporization, fusion and sublimation respectively.
Vaporization is the process of transformation of a liquid phase to its gaseous phase.
Fusion is the process of transformation of a solid phase to its liquid phase. So, it is also known as melting process.
Sublimation is the process of transformation of a solid phase to its gaseous phase directly without undergoing into the intermediate liquid phase.
The molar heat of vaporization is represented as
The molar heat of fusion is represented as
The molar heat of sublimation
