Cold air sinks and warm air rises. If you are in a warm room of your house and cold air starts leaking in from somewhere, you will feel the area closest to the floor getting colder first. Cold air displaces or takes the place of the hot air forcing the hotter air to rise above. If you have buzzards where you live, watch them over a field. They will circle in a column and rise higher and higher without flapping their wings. They are riding a thermal of warm air that has been heated by the sun. As the warm air rises the birds soar with it. Good proof that hot air rises is a hot air baloon. The hotter the air inside the baloon, the higher it goes.
