Quote:Yep! Thanks for the more technical explanation. It's fascinating how what seems like common sense (i.e. get closer to the sun = higher temperatures) can be quite wrong.

 

The equation you are looking for is: PV=nRT.

 

Everything else being constant, as pressure goes down, so does temperature.

 

As for explaining it to most people, I just say, when you go high, you get closer to outer space.  And space is really, really, cold.

 

On topic, I can accept the integration of trigonometric functions, but really can't justify in my brain.  It was the point in calculus when I realized I would never be a mathematician.  I could understand all the laws of math up to that point.
