Abstract : The enthalpy apparatus was modified to permit operation at reduced pressure in the nitrogen boil-off chamber of the calorimeter. A temperature of 125 R is now obtainable compared with 150 R previously obtainable. This increases the number of points which can be measured with liquid nitrogen. The remaining points can be measured in a static calorimeter with liquid helium as the refrigerant. This modification will avoid the safety problems related to operation with liquid hydrogen.
