Air Pressure

What is air pressure?

Air pressure is a force exerted, (apply or bring to bear; a force, influence, or quality), on a surface by the weight of the air. The pressure of the atmospheric or compressed air. The pressure within a container due to the compression of air.

Well if you picked any three of those your right. Air pressure is all those things. But there is something that has to be for air pressure to even exist…air has weight. Believe it or not it is logical, how can something exert pressure if it doesn’t weight anything? That also explains why a tank of helium is so heavy with you first by it, and when you throw it away. What is the only thing that has changed? First there was helium inside, and now, there isn’t!

How you ever pumped a tire and it exploded, I haven’t, but the reason this happens is because of the air pressure was so strong it popped the tire. It’s like filling a balloon with water, the water makes the balloon grow, because of the water pressure, until the pressure is too great for the balloon and it bursts, as well as your mother for getting the whole kitchen wet.

In fact you can even prove air pressure exists! All you need is a balloon and start pumping it with air, keep doing this until it pops, the air pressure was so strong it broke the balloon, the loud popping sound is the air rushing out.

  1. The airmass at the lower levels is more dense with maybe 90% of molecules being there but if you go high enough the process equalizes and above that the process is reversed with air expanding outward and the lack of pressure… In Weather we have the Level of Free Convection in which upward vertical motion is no inhibited by the atmosphere. Because this is a relative matter with the time of year being one example affecting density these levels are adjusted to the relative density of the times.
