Specific Heats and Enthalpies of Technical Solids at Low Temperatures

A Tabulation of the Thermodynamic Properties of Normal Hydrogen from Low Temperatures to 300° K and from 1 to 100 Atmospheres

Pressure, volume, temperature, internal energy, enthalpy, and entropy of normal hydrogen gas have been tabulated along isobars temperature to 300°K and from a pressure of 1 to 100 atmospheres. The source of data is the Research Paper 1932 of the National Bureau of Standards Journal of Research. The method is described by which the data presented in Research Paper 1932 is reduced to properties directly useful for engineering calculations. A method is also described for estimating the effect of ortho-para compositions upon the tabulated properties. Tabular values are presented in the dimensional units of the metric system. The tabulations are also available in the dimensional units of the British system as Technical Note no. 120, Supplement A.
