THE MOLECULAR THEORY OF GASES 79
Interdependence of the gaseous laws. Kinetic theory of gases:
Bernoulli, Waterston, Clausius, Maxwell, Boltzmann, Schmidt,
Graham. Gaseous diffusion. Van der Waals’s equation. Ratio
of specific heats: Kundt and Warburg. Liquefaction of gases.
Critical temperatures and pressures: Andrews, Pictet and
Cailletet, Wroblewski, Olszewki, Dewar, Kammerlingh Onnes.
Liquefaction of air on the large scale. Research at low
temperatures.
