take a balloon fill one with hot air and one with cold air
then the hot air balloon would rise up
and one more can be demonstrated with the land and sea breeze.

Hello!
Here is your answer!
==========================================================
Hot air is less dense than cold air therefore it is lighter
The reason this happens has to do with the nature of heat.
-When an object or substance heats up, the atoms which compose it start to move and vibrate more quickly.
-This vibration pushes them apart, causing them to take up more space. That means that a given volume of air (or water, or whatever) will have fewer atoms in it, because some of them were pushed out as it expanded.
-Fewer atoms means less mass, means less weight per volume. Less weight per volume means less density.

Hope it helps!
