Let us analyse the technique of producing vacuum.
Initially the pressure inside the container and that outside will be the same. While pumping out with piston model, we depend mainly on the functions of the valve operating in the evacuating device. Actually valve is a traffic controller who checks the one way traffic. There by the valves are expected to get open only in one direction and thereby allowing the air to move only in one direction. As the pressure goes on reduced to some level, then the air pressure inside the container will become so weak that it cannot even push the valve gate to get opened and come out. This draw back is there in the old devices.
So rotary pump got designed where the rotor would suck those weaker molecules to come out of the container.
Even after following so many techniques in an intelligent way to produce vacuum of the order of 10 -14 mm of Mercury, yet some molecules thousands in number) will be roaming about within the container. So it is impossible to produce perfect vacuum.
In free space too, there are hydrogen molecules with utmost very low density some ten molecules for every cubic meter.
as near perfect as possible

It is technically possible for three teams in one conference to have perfect seasons.
In the low pressure side of a steam turbine, the vacuum is maintained by the condensation of steam in the condenser. At high loads, the condenser may not satisify the demand, allowing steam to remain gaseous for a longer period of time. This can cause pressure to rise.
It's purpose was to act like an amplifier and a switch. Without any moving parts, vacuum tubes could take very weak signals and make the signal stronger (amplify it). Vacuum tubes could also stop and start the flow of electricity instantly (switch). These two properties made the ENIAC computer possible.
A Perfect Vacuum was created in 1971.
No, a perfect vacuum has not been made.
If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.
Maximum possible vacuum is -0.1 Mpa
1. The perfect, complete vacuum is impossible.2. You need a vacuum ionic pump down to approx. 10 ex.-11 bar.
Yes, this would be perfect symmetry.
No scientists can hardly produce a close to perfect vacuum in a high tec. lab, So I very serously doubt you could make a perfect vaccum in a bottle.
That depends on the density of the material. For example, 280,000 gallons of a perfect vacuum have a mass of zero tonnes.That depends on the density of the material.

In the space occupied by a perfect vacuum.
It's a space where there is no matter. A perfect vacuum will have no gas particles at all.
