Ah I get it now. Thanks once again.

Acctually when I look back at this now I'm a bit confused. I understand that in the "molecular" explanation that gravity is the driving force, making air closer to the ground denser making air pressure greater etc. The problem is that I don't see how these are two ways of representing the...

In Physics classes at college I was taught that atmospheric pressure is due to the weight of the air above a body. I understand this and all related equations and concepts. But just the other day I was reading up on gas laws in a chemistry book. In that book it stated that atmospheric...
