Fig. 30. The decay of phosphorescent quinoline-A in durene at 1.25 K. Abscissa 0.2 sec per division. The delayed signal is induced by sweeping through the X—Z transition at 3585 MHz, 1.28 sec after shutting off the exciting light. (From Schmidt, Antheunis, vander Waals, Ref. >)... Fig. 30.

In general, the state of a system may be described by any two of the three variables p, V, and T. Thus, accdg to the "principle of corresponding states , any dimensionless group is a universal function of any two of the three reduced variables. In particular the compressibility factor, pV/RT of vander Waals equation of state, can be written as a universal function of the reduced volume and te mperature ... [Pg.195]

In order to explain the deviations of real gases from ideal behaviour vander Waals suggested that it is necessary to modify the kinetic theory of gases. The following two postulates of the kinetic theory, according to him, do not appear to hold good under all conditions. [Pg.71]

So, it is necessary to apply suitable corrections to the ideal gas equation to make it applicable to real gases, vander Waals introduced two correction terms in the ideal gas equation to account for the errors introduced as a result of neglecting the volume of the molecules and intermolecular forces of attraction. [Pg.71]
