Abstract : Experimental programs on parahydrogen at this laboratory have provided pressure-density-temperature relations and heat capacities and heat capacities at temperatures from 15 to 100 K and at pressures from 2 to 350 atm. The two types of data have been correlated to yield a consistent set of functions. The properties tabulated for selected isobars and isochores are temperature, volume or pressure, the isotherm derivative, the isochore derivative, internal energy, enthalpy, entropy, the specific heats at constant volume and at constant pressure, and the velocity of sound. Also presented are then derived Joule-Thomson inversion curve and some comparisons with normal hydrogen near 100 K.
