Why Does Hot Air Rise - UCSB Science Line
http://scienceline.ucsb.edu/getkey.php?key=3901
webAnswer 1: Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water …
