Abstract
Volumetric behavior of carbon saturated vapor, in the temperature range 2500–3200 K, is described by two approaches: by the truncated form of the virial equation for the real monatomic gas and by the ideal gas equation of state for the mixture of present C i , species. The literature data for C i , partial pressure and \(\Delta _\upsilon H_{0,{\text{C}}_i }^0 \) are analyzed through the comparison of the vapor pressure values deduced by the first approach with the data. New data for p 3 and \(\Delta _\upsilon H_{0,{\text{C}}_3 }^0 \) are then evaluated. The values for carbon vapor pressure and saturated vapor molar volume calculated by two different approaches show remarkable agreement.
