(II) Wine bottles are never completely filled: a small volume
of air is left in the glass bottle's cylindrically shaped neck
(inner diameter d 18.5 mm) to allow for wine's fairly
large coefficient of thermal expansion. The distance H
between the surface of the liquid contents and the bottom of
the cork is called the "headspace height" (Fig. 17-21), and is
