Final answer:

Hot air balloons work because hot air is less dense than cool air, creating a buoyant force.


Explanation:

In a hot air balloon, the hot air is less dense than the surrounding cool air due to thermal expansion. This buoyant force allows the balloon to rise as the less dense hot air floats above the denser cool air.
