If a 1.5-cubic-foot cylinder can hold 306 cubic feet of oxygen, the oxygen must be under a bit of pressure, yes? The 306 cubic feet of oxygen are at one-atmosphere pressure (15 psi or so). When I calculate the volume of an ideal gas occupying 306 cubic feet at 15 psi, when under a pressure of 2400 psi, I get about 1.9 cubic feet. Presumably the oxygen liquifies under that much pressure, and occupies a slightly smaller volume. Dan Berger MadSci Administrator
