Eleven equations of state are employed to predict the vapor pressures, liquid and vapor densities, liquid and vapor heat capacities, and vaporization enthalpies and entropies of normal hydrogen along the coexistence curve. The volumetric and thermal properties of gaseous hydrogen together with the speeds of sound, Joule-Thomson coefficients and inversion curves for wide ranges of temperature and pressure are predicted as well. The results are compared with experimental data and the recommended values of standard thermodynamic tables. The best equations of state in predicting the properties of hydrogen (saturated and supercritical) are introduced and reported.
