Abstract
In the article on the base of the modernized physical chemistry model “the perfect gas” of the assuming the presence in it chemical energy and theory of thermodynamic potentials is produced a study of the isothermal expansion of perfect gas. The examination of this phenomenon is realized both for that reversed and not reversed of the versions of the development of process, including this limiting case as the expansion of perfect gas into the void. In the work, the possibility of investigating the process of expanding the perfect gas with the use of a method of thermodynamic potentials is revealed and substantiated. On the basis of the analysis conducted are obtained the results analogous obtained with a study of the data of processes by traditional method. From other side the application “chemical” and “electrochemical” methods of study made it possible to increase the arsenal of the means of those utilized for the isothermal expansion of perfect gas and to obtain the adequate explanation of the effects of local heating and cooling and number of other phenomena, which occur with conducting of the classical experience of GayLussac.
