Does hot air really rise? - Physics Stack Exchange
https://physics.stackexchange.com/questions/6329/does-hot-air-really-rise
WEBTo answer the question exactlty, hot air does rise, and it is also displaced by cold air (though often from the side, not directly above it). And yes, gravity is the reason less dense liquids like to sit on top of more dense liquids

Why does hot air rise and cold air stays at the bottom? Is it …
https://scienceline.ucsb.edu/getkey.php?key=563
WEBAnswer 1: Essentially yes. When air becomes hot it is because it is absorbing energy in the form of heat. The absorbed energy makes the molecules in air move and expand, therefore decreasing the airs density. The opposite is true for cold air.

Does Hot Air Always Rise? | Wonderopolis
https://www.wonderopolis.org/wonder/does-hot-air-always-rise
WEBDec 13, 2016 · Hot air does rise, but it doesn't have anything to do with getting closer to the Sun. Hot air rises because gases expand as they heat up. When air heats up and expands, its density also decreases. The warmer, less dense air effectively floats on top of the colder, denser air below it.

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 because wood is less dense than water.

What happens when warm air rises and cold air sinks? - UC …
http://scienceline.ucsb.edu/getkey.php?key=5994
WEBAnswer 1: The movement of hot and cold air is very important for moving heat and energy around our planet Earth. Hot air is less ‘dense’ than cold air. In case you do not know the word ‘dense’ yet, I essentially mean that hot air is lighter and cold air is heavier. Therefore, hot air rises and cold air sinks. Now, what happens?
