THE difficulty of reconciling line spectra with the kinetic theory of gases, has been referred to by Prof. Fitzgerald (NATURE, January 3, p. 221). The following considerations show that it is ...

THE difficulties in the way of harmonising the spectroscopic phenomena of heated gases with the conclusions of the Boltzmann-Maxwell theorem of distribution of kinetic energy, appear to me to have ...

This step looks at the behaviour of a fixed quantity of gas under varying pressure, volume and temperature. The kinetic theory model can be used to explain the properties of solids, liquids and ...
