Exactly, it's all about low pressure whether it's mildly lower or extremely lower...but it all counts in determining the outcome of things placed into that environment as to what changes we see, because this impacts what is going on in that sky above and is on the same lines as the higher to lower pressures we are under at sea level and high in that sky.I don't believe there is a vacuum. Lower pressure, certainly.
For perhaps the hundredth time a vaccum doesn't mean nothing - it is simply a measure of pressure approaching a theoretical limit (similar to absolute zero) you can get close to a total vacuum but to current knowledge not to it.
Some say it's so close as to be so, barring some scattered molecules/matter just floating about in a nothingness, as we're told.NOBODY says space is an absolute vaccum.
Do you believe the air is sucked out of a container or do you believe there is something else going on with the pump?For a bell jar PV = nRT again, you remove n moles of gas from a fixed volume and as PV stays constant and the volume is fixed the pressure must fall as the remainder of the material left in the jar expands to fill the available space, this is how vacuum pumps and vacuum engines (which I use daily) work. Sits back and waits for the drivel about not removing stuff just the space between the atoms gets bigger and the same amount stays in the bell jar even though the weight reduces as you pump out the contents.
I'd be interested to see your answer to this and your explanation for whatever your answer is.
Can you explain how the air is evacuated?
