Abstract
Graphical examination of Maxwell's rule is employed with Van der Waals' equations to give a graphical relation of saturation vapor pressure to temperature from the law of corresponding states. An analytic approximation is compared with experiment and with an approximation for the experimental mean curve. Phenomenological arguments are employed to derive the latent heat of evaporation of the liquid and the critical temperature of the vapor in terms that are correct to a first approximation for all substances.
