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.
Typically, hot air balloons are filled with propane gas to heat the air inside the balloon and make it 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.
A hot air balloon uses propane gas to heat the air inside the balloon. As the air inside the balloon becomes warmer and less dense than the surrounding air, it creates lift, allowing the balloon to rise. The burner, which is powered by the propane, heats the air to enable the balloon to ascend.
The gas filled in hot air balloons to make them rise is called propane or natural gas. It is heated to create a lighter-than-air gas that provides lift to the balloon.
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
Hot air balloons typically use propane gas as fuel to heat the air inside the balloon's envelope. The propane burners heat the air, causing the balloon to rise and fly.

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.
