Just plain old ordinary air, but heated by the flame of the burner (which I believe burns propane gas).
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.
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.
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.
A typical hot air balloon is filled with the same air we breath.
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.

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

The pressure inside a balloon is determined by factors such as the amount of air or gas in the balloon, the volume of the balloon, and the temperature of the air or gas inside. As more air or gas is added to the balloon, the pressure will increase. Conversely, if air or gas is released from the balloon, the pressure will decrease.

It is lighter than air
It's a gas. The air molecules are free to move around anywhere in the balloon.
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.
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
