Abstract: The relationships between the ratio of molar enthalpy increase in the interval (0 К—T_f) to molar volume, the linear thermal expansion in the in­terval (273 К—T_f ) and the fraction of atoms (molecules) of inorganic sub­stances with molar enthalpy of the liquid state on the one hand and the mechanical properties of these substances such as hardness, tensile strength, and plasticity on the other hand have been analyzed. The ratio of molar enthalpy increase to molar volume has been used as a criterion of tensile strength and hardness of the solid substances. The plasticity of elements is interpreted from the viewpoint of the range of action of attractive forces in the solid state and of the value of the fraction of atoms with molar enthalpy of the liquid state.
