Hot air balloons heat up contained air so that the density of it becomes significantly less than the outside air and thus the container (balloon) will rise of float in the surrounding air until the density difference is null. Buoyancy is just that, less dense substances floating or rising in more dense substances. The other approach is saying more dense substances sink in less dense substance.

Bouyancy, pressure, and gravity.
What are some disadvantages of hot air balloons?
Hot air balloons are a slower form of transportation. For most people, they are beautiful to see when they are in the air.
What is a hot air ballons air pressure?
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
Why do balloons float up into the air?
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.
What happens to the density of air as it's temperature increases?
Becomes lighter and rises, the principle of hot air balloons.

What is buoyancy and does it relate to balloons?
For a full explanation of how the buoyancy principle works and how it relates the helium and hot air balloons go to the related question "What is the buoyancy principle?" in the Related Questions section below.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
What last longer helium fill balloon or hot air balloons?
hot air balloons
Why do hot air balloons work?
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
