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