it runs on propane.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.

Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
The upthrust exerted by surrounding air on the balloon.
The hot air, inside of it is very light and makes the balloon rise up.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
The heating of the air through the use of a burner is what makes balloons rise.
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Heating the air in the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. As the air inside the balloon cools, it becomes denser and the balloon descends. This process allows the pilot to control the altitude of the balloon.

Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
