Hi, I have a problem to understand one small thing. They say that air pressure per square cm at sea level is approximately 1 kg.
So at 2 sq cm it will be 2 kg, at 3 sq cm it will be 3 kg etc.
But... Here where I have a problem. The thing is that inside 2 square cm you can put 4 one square cm. Inside 3 square cm you can put nine square cm.
Just look at it this way:
2sq= 4= 1sq+1sq+1sq+1sq
3sq= 9 =
1sq+1sq+1sq+1sq+1sq+1sq+1sq+1sq+1sq
You see? So according to this logic the air pressure supposed to grow exponentially when you increase the surface, but according to textbooks it's not. Why?
It's supposed to be 1 kg at 1 sq cm, 4 kg at 2 sq cm, 9 kg at 3 cm etc.
See my trouble?
