The thermodynamic properties of liquid gallium are investigated from an effective pair interaction between ions, which explains the properties of the crystalline phases at 0 K for this metal. The results of pseudopotential theory are used and the thermodynamic perturbation method associated with the Gibbs‐Bogoliubov inequality. Computed values agree with the experimental data for volume, compressibility, latent heat, and auto‐diffusion coefficient. Some particularities are predicted of gallium such as low melting point and the fact that the liquid is more compact than the stable crystalline phase.
