Generalized correlations have been prepared for the internal energy deviation function and the thermal expansion coefficient of normal liquids at their saturation states. The new correlation of thermal expansion coefficient complements a previously published correlation of isothermal compressibility to complete the general description of the mechanical properties of saturated normal liquids. The new correlations combine to provide a general description of the configurational energy of liquids not far removed from their saturation states. As such, they are needed in the thermodynamic calculations for nearly-ideal systems. The correlations can be useful for other purposes, such as heat balance calculations for non-flow systems.
