Thermodynamic Properties of Selected Species Containing Carbon, Hydrogen, Oxygen, Helium and Argon
Abstract
In the course of research work on detonation in gaseous mixtures, the authors found a need for reliable and consistent values, at small temperature intervals, of the thermodynamic properties of a number of species involving the elements carbon, hydrogen, oxygen, helium and argon. This report presents the results of calculations of six thermodynamic functions at 10K intervals for twenty-seven selected species, including monatomic carbon in both the gaseous and solid phases. The basic thermodynamic data from which the computations were made (heat capacity, free energy and enthalpy data) were gathered from reliable sources, all such data being found at 100K intervals. Other thermodynamic functions were computed from the basic data, and all of the 100 data were treated to insure internal consistency throughout. Highly consistent values of all of the thermodynamic functions at 10K intervals were then obtained by the Aitkens fourth degree interpolation method. The temperature range covered for the majority of the species is 100oK to 6000K. The thermodynamic functions presented, in dimensionless form, are racial heat capacity at constant pressure, free energy, enthalpy, heat of formation,entropy, and equilibrium constant.
