Air particles contain oxygen.
particles of cool air are sloser together than particles of warm air
it is important to separate and purify substances so that: 1.we can get them in their pure form. 2.to remove undesirable particles from them.

Yes, air particles can stick to petroleum jelly. Petroleum jelly is a sticky substance that can trap and hold onto particles, including particles in the air.
Particles in the air are closer together in solid objects and liquids, where the particles are tightly packed. In these states, particles are closely bonded and have less space between them compared to the surrounding air.
When air particles are further apart, you have low air density. This can result in lower air pressure.
Usually by a combination of air jets and filter screens.
