But, No Gas, No Pressure

If pressure is solely due to temperature particles, why would a vacuum not exert a pressure on the walls of a containment maintained at a constant temperature?

Temperature particles are charged particles.  Temperature particles of the same charge repel each other.  Pressure on the containment wall is due to \(T\) particles, attracted by the \(T\) particles (of the opposite charge) on the gas, distributed on the inside wall of the containment.


Without a gas inside the containment, the charged particles move to the outside surface of the containment.


There is no pressure inside the containment, but the \(T\) particles on the outside, still causes an outward stain on the containment.  The associated stress acts against the pressure crushing the containment inwards.

Reducing temperature on the containment reduces this outward force and allows outside pressure to collapse the containment.
