Best Answer

Propane gas is used to fuel the burners that heat the air inside the balloon.
A hot air balloon is filled with regular air that's heated by a propane burner. This heated air has a lower density than the air outside the ballon, thus allowing the filled balloon to be buoyant.

What happens to volume and mass in a hot air balloon?

When the air is heated inside the balloon, it expands, causing it to be lighter than the surrounding (and presumably) cooler air. One imagines however, that as the air inside the balloon is heated, some air is forced out (due to expansion), thus resulting in a decrease in the entire apparatus' overall mass (not to mention a decrease in mass due to any fuel's having been used to heat the air in the balloon).


What kind of gas is used for air balloon?

Just plain old ordinary air, but heated by the flame of the burner (which I believe burns propane gas).
