文摘

We present Theoretical Calculations for the Liquid–Vapor Coexistence (LVC) curve of fluid Hydrogen within the first order perturbation theory with a suitable first order quantum correction to the free energy. In the present equation of state, we incorporate the dimerization of H₂${}_2$ molecule by treating the fluid as a hard convex body fluid. The thermophysical properties of fluid H₂${}_2$ along the LVC curve, including the pressure–temperature dependence, density–temperature asymmetry, volume expansivity, entropy and enthalpy, are calculated and compared with computer simulation and empirical results.
