A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
The type of gas you put in a hot -air- balloon is either propane, or helium. we used to use hydrogen because it was lighter than air, but, it was very flammable to where even a little spark could light hydrogen and burn a house down.
A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
Any gas that is more dense than air.Answer:It is a bit more complex than that - an air filled balloon would still fall because air has the density of air. In a normal inflated balloon the air in the balloon is compressed and has a density more than uncompressed air. If the "balloon" were a plastic bag wiith no air pressure above the pressure of the surrounding air, the balloon would still fall as the combined (average) density of the balloon/bag system is greater than the surrounding air. Even if the balloon were filled with a gas with a lower specific gravity than air the balloon wll fall if the compressed gas density excedes that of the surrounding air or if the combined (average) density of the balloon/bag or balloon system is greater than the surrounding air.
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
Helium is normally used in balloons that float. Helium is the second lightest gas. Hydrogen is lighter, but it is also flammable and thus dangerous.When normal air is used to fill a balloon, the balloon will not be buoyant.If you fill a balloon with air from your lungs, there is a bit more water vapor and a bit more carbon dioxide and a bit less oxygen in the air inside the balloon, but that has a small impact on the buoyancy.The larger balloons that carry people are called hot air balloons because they are filled with hot air. They are buoyant because the hot air is fractionally lighter than normal air but there is a lot of it.Weather balloons and party balloons both use helium gas.As long as the gas plus the balloon is lighter than the air it displaces, the balloon will float in the air.Helium is normally used in balloons that float.

Helium gas is used in a balloon vendor.
The gas is hot air.
A typical hot air balloon is filled with the same air we breath.
Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.
propane
No, it is a gas balloon. It relies on lighter than air gases (helium or hydrogen) to provide buoyancy.
It is lighter than air
It's a gas. The air molecules are free to move around anywhere in the balloon.
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.
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
They use propane to heat regular air in the balloon. \The canopy of the balloon only holds heated air, the propane is held in a tank and is only used to create heat.
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
