and the pressures are measured by a gauge pressure trans-
ducer. Provisions are made for conveniently charging and discharging gases at controlled rates,
for optimizing the relative sizes of the sample chambers and expansion volumes, and for cleans-
ing the samples of vapors which would render equations (1), (2), and (3) inadequate to describe
behavior.
