PV=nrT
If the number of molecules is constant (not adding or removing from the system) then PV=T*constant
Constant = PV/T
V is the volume of the container. If you compress the gas by 100 times (1/100 the volume), at the same temperature, which the same number of molecules, the pressure goes up 100 times.
If you increase pressure without changing the number of molecules or volume, then temperature has to change.
SpaceX package has constant volume and changing number of molecules so P and T will shift around. Higher temp -> higher pressure.
The tank has fixed volume, but we can view it as V is reduced by 1:100, imagine there is an invisible tank that's 100 times larger, then those air is squeezed into smaller size. So P will increase 100 fold if temperature remains unchanged. P will increase 200 fold if temperature doubles.
