You believe you can pull gas out of a container. I'm asking you how you manage this. What are you using to do this?
Let's make this easier.
Go and get a plastic bottle. Open the lid and you have a plastic bottle full of air that is the same pressure as the normal atmospheric conditions you are standing in.
You want to evacuate this bottle of some pressure.
There's two ways you can do this. You can place your mouth over it and create a low pressure in your own mouth to allow the atmosphere to crush the bottle and push out the air into your mouth and out through your nose, or you can crush it yourself and push out the air in the bottle.
However, when it comes to a bell jar or a solid container we have something a bit different because we are evacuating the jar of some of the pressure but also stopping the external pressure breaching the jar or crushing it.
First of all we have to get the air out of the jar.
For this we need a pump and that pump is the creator of low pressure by pushing against external higher pressure.
It does not suck anything out of the jar, it pushes against the atmosphere and creates that lower pressure where the air in the jar can expand out by it's very own decompression, molecules against molecules.
As an analogy:
As if you filled a jar full of soft air balls and crammed them into the jar and opened that jar against lesser pressure. The balls would be pushed out by the rest of the compressed balls so your air balls closest to the opening would be pushed out.
This will keep happening as long as the pressure at the opening is less than the pressure created by the decompression of the air balls inside the jar.
If externally those air balls were the same as in the jar then the air balls in that jar would remain in that jar because the pressure is equalised.
Add a pump and this pump can push away (compress) the external balls away, enough to allow decompression of the air balls in that jar.
The same with gases.
Maybe some people will understand what I'm saying......but.
Utter, utter shit - it is impressive that a single person is stupid enough to get so many principles wrong in such a short time you literally do not have a clue. Go and read a book (assuming you can). You are thicker than whale spunk. Anybody who can understand the utter shite you type is a stupid as you. You have no idea at all......and to cap it all utterly ignorant with it. I can tolerate stupidity but utter wilful ignorance is beyond the pale.
I literally spend my whole working day moving gases and liquids around with compressors, pumps, fans, ejectors, air movers etc. and you are so utterly wrong it is astounding.
