Changes of the first and second kind, according to our views of the constitution of molecules, are probably of very rare occurrence; in fact, chemical action appears almost always to involve the occurrence of both these kinds of change, for, as already pointed out, we must assume that the molecules of hydrogen, oxygen and several other elements are diatomic, or that they consist of two atoms.

The well-known experiments of Regnault and Wiedemann on the specific heat of gases at constant pressure agree in showing that the _molecular specific heat,_ or the thermal capacity of the molecular weight in grammes, is approximately independent of the temperature and pressure in case of the more stable diatomic gases, such as H2, O2, N2, CO, &c., and has nearly the same value for each gas.
