Upon melting, a part of ethylene-chloride molecules in trans-form in the solid state changes into gauche-form. The partition function for the material was developed according to the significant structure theory of liquid proposed by H. Eyring and his co-workers, and the parameters Es, θ, Vs, and a, therein, are determined by the manner developed by Chang, et al. The molar volume, vapor pressure, vaporization entropy, critical point properties and surface tension of the liquid were calculated. The results are in good agreement with experimental values.
