No, a perfect vacuum has not been made.
In a perfect vacuum, the pressure is zero psi.
The pressure measurement of a perfect vacuum is 0 psi.
The ideal pressure in a perfect vacuum is 0 psi.
The density of a vacuum is essentially zero because it contains no matter. In a perfect vacuum, there are no particles present to contribute to a measurable density.
A perfect vacuum would contain no particles, so no sound can travel through it since sound requires a medium such as air, water, or a solid to propagate. Vacuum is an ideal situation, but in practice, it is difficult to achieve a perfect vacuum.
A Perfect Vacuum was created in 1971.
In a perfect vacuum, the pressure is zero psi.
The pressure measurement of a perfect vacuum is 0 psi.
The ideal pressure in a perfect vacuum is 0 psi.
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.
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.
A perfect vacuum
In the space occupied by a perfect vacuum.
