What is the principle behind in hot air balloon?

Hot air balloons operate on the principle of buoyancy, where the warm air inside the balloon is lighter than the cooler air outside, causing the balloon to float. By heating the air inside the balloon using a burner, the overall density decreases, allowing the balloon to rise.


What is in a hot air balloon to make it fly?

Hot air balloons fly due to the principle of buoyancy. Heated air inside the balloon is lighter than the cooler air surrounding it, causing the balloon to rise. The burner inside the balloon heats the air, which expands and becomes less dense, lifting the balloon off the ground.


Why do you use hot air for hot air balloon instead of cool air?

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.


Does a hot air balloon need CO2 to lift?

No, a hot air balloon does not need CO2 to lift. Hot air balloons work on the principle that hot air is less dense than cooler air, causing it to rise. When the air inside the balloon is heated, it becomes lighter than the surrounding air, allowing the balloon to lift off the ground.


How did the first hot air balloon work?

The first hot air balloon, created by the Montgolfier brothers in 1783, worked by heating air inside a silk and paper envelope. When the air inside the balloon was heated, it became less dense than the surrounding air, causing the balloon to rise. This principle, known as hot air or thermal buoyancy, allowed the balloon to float in the sky.
