Volume and pressure do not inherently require a solid container. This video connects molecular motion, entropy, atmospheric density, and gravity to explain why air pressure decreases with altitude. Without a downward force, gas would tend toward a more uniform distribution rather than maintaining the observed vertical pressure gradient.
