This is a properties dependent question requiring further information to provide a more specific and complete answer. As an example, this gas, like most gases, is confined to follow the general Gas Laws (e.g., Boyles Law, et.al.). Carbon dioxide exists on earth in all 3 of the states of matter: Gas, liquid, and solid. The state it's in at any particular time is a function of a few different factors. One of those being temperature; as most people are aware, when it is very cold it is a solid as in dry ice, when not as cold it can be a liquid that begins to boil when the temp. Exceeds the boiling point, a temp. Still below that of water ice. Another factor that influences which state of matter a substance occupies is the physical pressure exerted on it. When a substance transistions from a solid or liquid to a gas it exerts a vapor pressure that is characteristic of each substance and further dependent on the size of the containment vessel, if any, and if the material concentration is great enough for the vapor pressure to reach equilibrium.
To answer the question, one needs to know if the carbon dioxide is in a containment vessel; for any given size vessel at room temp. And pressure, the gas will disperse to fill the entire vessel to equilibrium, the point at which there are an equal number of carbon dioxide molecules, an amount that is the same for every unit of volume measured within the confinement space. If the temp. And pressure were specified, the number of cubic feet of carbon dioxide gas in a pound of liquid carbon dioxide would be determined by the volume of the container and whether the gases' density (a measure of the weight per unit of volume at a specified temp. And pressure.) had been given time to reach a steady state equilibrium where the density was no longer fluctuating but rather constant and fixed. This latter paragraph has particular application to the question because it involves the amount of the gas in a pipeline, which I believe most would assume to be an open pipeline and thus subject to the determining factors outlined above.
I hope this was of some further help. . . .If not, oh well! It was just a thought...BTB
