文摘

The internal pressures, \(P_{\mathrm{int}}\), of practically all the liquid metallic elements in the periodic table up to plutonium (except highly radioactive ones) at their melting points were calculated from data in the literature. They are compared with the respective cohesive energy densities, ced, obtained from the literature data too. The ratios \(P_{\mathrm{int}}{/}ced\) for various liquids are ranked as follows: molten salts < polar/hydrogen-bonded molecular solvents \(\sim \) liquid metals < room temperature ionic liquids < nonpolar molecular solvents, and the reverse of this list reflects the relative strengths of the mutual interactions of the particles constituting these liquids.
