Know the following about balloon flight:

A. How are molecules distributed in warmer air?

B. How are molecules distributed in cooler air?


Already looked around on google and stuff. I just need a more personal explaination - something in idiot language. Hah. +1 to first who can provide best/most answers.[/quote:3dea1]

Warm air rises, causing the baloon to rise.

simple as that.
