Book excerpt: Excerpt from A System of Physical Chemistry, Vol. 3 of 3 In this volume an attempt is made to deal with some physico-chemical applications of the principles of statistical mechanics. An account is first given of the application of what is now known as the classical statistical mechanics, more particularly to the problem of the energy content of substances and its variation with temperature, on the one hand, and to the problem of radiation on the other. It will be seen that in both these branches classical statistical mechanics makes it possible for us to advance very considerably beyond the limits set by the elementary kinetic theory employed in Volume I., but at the same time it will be found that the classical statistical mechanics does not furnish us with a complete and adequate basis for all the observed phenomena. It is therefore necessary to enlarge or modify the fundamental concepts of statistical mechanics, and it is precisely with this object in view that Planck has been led to introduce the idea of quanta. Planck's quantum theory is, therefore, properly speaking, a new or modified system of statistical mechanics. It happens, however, that Planck was led to his revolutionary changes by considerations based upon the observed facts of radiation, and for this reason it is usual to speak of the quantum theory of radiation. Radiation affords, as a matter of fact, one illustration, and a very striking one, of the applicability of the new mechanics. But even the success which has attended Planck's treatment of radiation problems would scarcely have sufficed to gain for his views that prominence which they now have, had it not been for the satisfactory explanation which his theory offers at the same time for the heat content of substances and the variation of the heat content with temperature. The idea of energy quanta has been applied in recent years to other types of physico-chemical phenomena, some of which will be considered.
