Air - a mixture of nitrogen, oxygen, carbon dioxide and other gases. When heated, air becomes less dense and so it will float in cooler (= more dense) air, giving the balloon its lift.
Airships and blimps are different to hot air balloons in that they gain lift from an envelope (the balloon) filled with a gas that is lighter than air. In the past, this was hydrogen but use of this gas was stopped due to its extremely flammable nature and helium is now used instead.
Used gasses in balloons: helium, hot air, hydrogen.
A typical hot air balloon is filled with the same air we breath.
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.
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.
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.
The fuel used in a hot air balloon is propane gas. It is ignited to heat the air inside the balloon envelope, making it less dense than the surrounding air and causing the balloon to rise.

propane
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.

It is lighter than air
The solid would be the basket and balloon, and the tanks holding flammable gas. The liquid is water vapor released by burning the gas. The gases are the fuel in the tank, and the heated air in the balloon that causes it to rise.

Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
