Agree it isnt a weight thing
The pressure change stuff is false. All gasses follow the same laws. Nitrogen and oxygen will act the same/
It is because you cannot buy high pressure bottles of *air*; that nitrogen is nice and cheap and inert; that you can buy it 'technical pure' and totally moisture free.
This last part is THE key: moisture. THAT is what caused the pressure changes w temp.
And the nitrogen they sell in shops is NOT the same that race cars and airplanes use.
