Understand your sentiments Lightning Male , but I'll try again....

Speedbird.

You keep saying:

Increased temperature results in lower pressure air
I and others keep telling you that is wrong, but for some reason you don't seem to grasp or accept this.

Here's 3 things to think about.

1. If higher temperatures equals lower pressures as you keep insisting (and presumably lower temperatures = higher pressures), how come pressure reduces with altitude (where both temperature and pressure, of course, reduce with altitude.) How could that be so if you were correct?

2. Here's some historic average surface pressure charts Note that the pressures are higher in the warmer areas (i.e. Southern England) than the cooler areas (i.e. Northern Scotland) and are higher in Summer than Winter. How could that be so if you were correct?

3. If pressure in a hot air ballon was lower than the surrounding air, it would collapse, so clearly its not. How could that be so if you were correct?


I'm happy to answer any further queries provided you don't include
Increased temperature results in lower pressure air
within the question , or I'll be forced to respond with a somewhat rude
