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.
No. A hot air balloon is a solid object. That is, the basket, the ropes, the burner and the envelope itself are not gasses. The air within the envelope is a gas, of course; heated atmospheric gasses in fact. But the balloon itself is not a gas.
It's a gas
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.

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.
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 is hot air.
Simple...hot air rises..
The hot air from the gas burner rises and enters the balloon's envelope. Once there is enough hot air trapped, the whole balloon will begin to lift off the floor. This is due entirely to the fact that hot air rises.
Yes, a hot air balloon is an example of thermal expansion in gas. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air, causing the balloon to rise.
No, hot air balloons, as the name suggests, contain hot air, not helium.
