Abstract
Exact analytical expressions for the specific heats and the isentropic exponent are obtained for partially-ionized monatomic, pure diatomic, and heteronuclear diatomic gases. Since the specific heats and the isentropic exponent are analitically expressed in terms of concentration derivatives, the problem of the analytical expressions is reduced to the calculation of these derivatives. For a monatomic gas, four species (atom, monovalent and divalent ions, and electron) are taken into account. For a pure diatomic gas, five species (molecule, atom, molecular and atomic ions, and electron) are taken into account, and for a heteronuclear diatomic gas, seven species (molecule, two atoms, one molecular and two atomic ions, and electron) are included. The results of these expressions are in good agreement with published tables obtained by a numerical method over a wide range of temperature and pressure.Keywords
