Abstract : Work on detonation in gaseous mixtures requires reliable and consistent values, at small temperature intervals, of the thermodynamic properties of a number of species involving C, H, O, He and A. Results are presented of calculations of 6 thermodynamic functions at 10 K intervals for 27 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 100 K intervals. Other thermodynamic functions were computed from the basic data, and all of the 100 K data were treated to insure internal consistency throughout. Highly consistent values of all of the thermodynamic functions at 10 K intervals were then obtained by the Aitkens fourth degree interpolation method. The temperature range covered for the majority of the species is 100 to 6000 K. The thermodynamic functions presented, in dimensionless form, are molal heat capacity at constant pressure, free energy, enthalpy, heat of formation, entropy, and equilibrium constant. (Author)
