✦ Synopsis

Compressibility isotherms of hydrogen have been .measured upto a density of 939 Amagat at temperatures between 0°C and 150C. The virial coefficients have been calculated using only the measurements in the density region below 130 Amagat. Special attention has been paid to the accuracy obtainable for the values of the second virial coefficient. For interpolation purposes the measurements in the whole density range have been represented by the series P(V-~) ----A + ~d + yd 2 + ~d 3.

  1. Results. The compressibility isotherms of hydrogen have been determined at temperatures of 0 °, 25 °, 50 °, 75 °, 100 °, 125 °, 150°C and pressures u~to 3000 atmospheres, covering the density range upto 940 Amagat. Series I (densities 9 to 36 Am.) and series II (27 to 134 Am.) have been measured with the apparatus described previously 1 )2), using normalvolumes of respectively 1198,4 and 53,761 cm 3. Series III, IV, v, vI have been measured with the apparatus described by A. Michels, C. Michels and H. Wont e r s 3) using the normalvolumes:
