An atom is basically everything, what you see what you touch, and when two atoms connect, its called a mulicule. There are different parts of the atoms, the parts are proton, neutron, electron, and nucleus.
In an air compressure system. You put mulucles in and that means adding more air. When you put something in like for an example a t-shirt, and you dont push it down all the way where the air will push out. It wont work. It wont work beacuse there are gaps betwwen the mulicules and the t-shirt. Also it wont work if you dont put enough pressure into you system. You need enough PSI to launch whatever your luanching!
