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.
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.
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
One way to make a hot air balloon without fire is to use a heat source other than flame, such as a heat gun or hair dryer, to fill the balloon with hot air. The hot air will cause the balloon to rise and float. Make sure to use caution and follow proper safety measures when using alternative heat sources.
with out the hot air the balloon would not rise
Balloon propulsion and rocket propulsion both involve pushing against a fluid medium to create thrust. However, rockets use combustion of fuel to generate high-pressure gases for thrust, while balloons rely on the displacement of air by a lighter-than-air gas (like helium or hot air) to generate lift and propel the balloon.

A hot air balloon uses buoyancy to stay in the air. The air inside the balloon is heated, making it less dense than the surrounding air, causing the balloon to float.

Hot air balloons use the energy generated by heating the air inside the balloon with a propane burner. This heat creates a temperature differential that causes the balloon to rise. As the air inside the balloon cools, it descends, allowing the pilot to control the altitude of the balloon.
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
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.
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
