I was surprised by how much I was surprised by the very first fact -- that air molecules move around at extremely high speed of 450m/s, but just bump into each other cancelling this speed out, and this speed is based on pressure & temperature.

And it's due to this speed, despite air's low density, the force air exerts is enormous -- equivalent to 10 tons per square meter. Somehow, the human sandwich does not explode nor implode due to equivalent pressure coming from the other side and inside.



Note that diving to a depth of only 10m will double the external pressure on your body yet humans can easily survive this.

Indeed the all time record is >300m which is something like 32x pressure.

So it’s not merely that there is equivalent pressure from inside.


>this speed is based on pressure & temperature

I'd say that pressure & temperature are a consequence of the speed, not the other way around
