Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
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.
Yes
Hot air is used in hot air balloons because when the air inside the balloon is heated, it becomes less dense than the surrounding cool air, causing the balloon to rise. This buoyancy principle allows the balloon to ascend and float in the sky. Using cool air would not provide the necessary lift for the balloon to fly.
Hot air balloons typically use propane gas as fuel to heat the air inside the balloon envelope, which makes the balloon rise and float.
There are several types of hot air balloons, including traditional spherical shape balloons, special shape balloons (such as animals or objects), and solar balloons that use solar power for heating. Each type serves different purposes and offers unique designs.

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.
'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.
if you have a helicopter or a military grade hoover craft Hot-air balloons and gliders can be used
You may use airplanes or balloons (aeronautics).

The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Helium gas is commonly used to fly balloons due to its lighter-than-air properties. It is non-flammable and safe for use in balloons to provide the lift needed for them to float in the air.
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.
Hot air balloons are typically filled with heated air, which is lighter than the surrounding air and provides lift. Some balloons may also use helium or hydrogen gas for buoyancy, but hot air is the most commonly used lifting gas for traditional hot air balloons.
