| Abstract: | Based on the theory of molecular aggregation and the model for hard spherical molecule, an equation of state for molecular aggregation is derived by the statistical thermodynamic method. Then, the densities of saturated vapor of 5 melting metallic substances are calculated by using the equation of state, giving quite satisfactory results. In addition, the latent heat of vaporization of the same substances are determined by using the Clapeyron equation and the above equation of state. The results obtained are in good agreement with the experimental data. |
