How is a metal collaspes when air is pumped out of him with a vacuum pump?

One question in my Chem homework, I asked why a metal collaspes when air is removed with a vacuum tube in terms of a kinetic model Molecular. The help is very appreciated.

your question is not very clear to me, but I know that this phenomenon occurs because the air pressure is higher than the atmospheric pressure in the room may or may not use kinetic thoery to explain this phenomenon, is under the motion of molecules can affect the air molecules

The chapter ends in Missoula Mercantile building old Macy's near you called pressure-vacuum system and was thefinest known around – not a new application of the venerable MissoulaMercantile Co. in 1921.
