For fluids, there appears to be no upper density limitation on the equation of state, The lower density limit for isotherms near the critical temperature is the critical density. The equation of state gives a good description of all types of fluids, nonpolar (including long-chain hydrocarbons), polar, hydrogen-bonded, and metallic, at temperatures ranging from the triple point to the highest temperature for which there is experimental data. For solids, the equation of state is very accurate for all types considered, including covalent, molecular, metallic, and ionic systems. The experimental pvT data available for solids does not reveal any pressure or temperature limitations. An analysis of the importance and possible underlying physical significance of the terms in the equation of state is given.}, keywords = {400 DEGREES C, COMPRESSED LIQUIDS, DENSE FLUIDS, HIGH-PRESSURES, linear isotherm regularity, PVT PROPERTIES, SODIUM-CHLORIDE, TEMPERATURE, THERMODYNAMIC PROPERTIES, UNIVERSAL EQUATION}, isbn = {1520-6106}, url = {://000269252700022}, author = {Parsafar, G.
