The value of change in entropy corresponding to the vaporization of 2 .40 mol of water at given conditions has to be determined. Concept Introduction: The entropy of a substance is the measure of fluidity the molecule of a particular state has. It can be calculated by enthalpy of fusion and freezing temperature. Entropy of fusion is calculated for a process in which a substance changes from liquid form to solid form which results in decreasing its entropy.
