Abstract:
ON THE BASIS OF AN APPROXIMATELY GIVEN STATISTICAL SUM OF GAS MOLECULES, AN ANALYTICAL EXPRESSION FOR THE THERMODYNAMIC PROPERTIES OF DISSOCIATING AIR IS OBTAINED. At temperatures of the order of 200 C and higher, a noticeable excitation of the vibrational degrees of freedom of the air molecules sets in, and at temperatures of the order of 2000 decomposition of the molecules into atoms-dissociation-sets in. At the same time the processes of excitation of new vibrational and electronic levels, and also the process of excitation of those rotational levels which depend upon the stiffness of the connection of atoms to molecules, continues. To take into account all ofatively simple and accurate representations for the thermodynamic functions of dissociating air if we neglect the processes of excitation of the extra degrees of freedom of the molecules.
