WebJan 4, 2024 · Guess what? It isn't! There are still air molecules that take up space inside that orange juice container. But, if you could suck out all of those air molecules, you would have a vacuum. WebIf your vacuum system has 1 cc of volume for each sq. cm of surface area, then since there are about 10 15 molecules per cm2, putting a single monolayer into the vacuum would increase the pressure by 3 x 10 -2 Torr (pretty big). If only 1 molecule in 10 6 is in the gas phase at any time, the base pressure is still only in the 8's.

WebJan 4, 2024 · A vacuum is a volume that encloses little or no matter. In other words, it is a region that has a gaseous pressure much lower than that of atmospheric pressure. A partial vacuum is a vacuum with low amounts of matter enclosed. A total, perfect, or absolute vacuum has no matter enclosed.
This vacuum state is called high vacuum, and the study of fluid flows in this regime is called particle gas dynamics.
