Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is
squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.

What makes a hot air balloon float?
A hot air balloon is able to float because the hot air being released into the balloon is less dense than the colder air surrounding it. Basically, the burner under the hot air balloons fills the balloons with hot air, enabling the balloon to rise through the cooler air outside.

How does a candle powered hot air balloon work?

What happens to hotair balloon on the moon?

How does hot air balloon work?

8J
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
