Constants| Periodic Table Part A 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 (Figure 1), and is typically H 1.5 cm for a 750-m bottle filled at 20 °C. Due to its...
