This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
The thrust of a hot air balloon is generated by the buoyancy principle: the lighter-than-air hot air in the balloon causes it to float upwards. Hot air balloons do not have engines or propulsion systems like traditional aircraft.
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
Hot air balloons float because hot air displaces cool air in the atmosphere
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
People think that hot air balloons where made for battles.

Hot Air
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Hot air balloons are now mostly used for leisure
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
It is simply air that has been heated. Hence the namehot air balloons are filled with hot air from a propane tank
