WebDec 8, 2024 · Using the ideal gas law (PV = nRT) it can be argued that the pressure of a gas goes up as the volume of the gas decreases. So as the available gas headspace volume in a bottle decreases, the pressure should increase. For these reasons, more fluid in the bottle (which results in less headspace) would create greater pressure - if all else is equal.
