Abstract
The author has proposed a theoretical equation for the nonequilibrium state of gases (TENSG), that is extended here to the theoretical calculation of gaseous heat capacity. Thus an equation of the heat capacity of gases at constant pressure is derived. This equation applies to both polar and nonpolar gases, the average error from 2398 experimental values being 0.38% based on 538 compounds. The method is far better than all other published methods.
Resume
L’auteur propose une équation théorique pour les états hors équilibre des gaz et l’applique au calcul théorique de la capacité calorifique des gaz. On obtient ainsi une équation donnant la capacité calorifique des gaz à pression constante. En appliquant cette équation, à la fois au gaz polaires et non-polaires, on obtient un écart, avec 2398 valeurs expérimentales issues de 538 composés, de 0,38%. Cette méthode est nettement plus satisfaisante que celles publiées jusqu’à présent.
