Why do helium balloons float?

Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.


Why do balloons float in the air?

Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.


How does helium help balloons?

Helium is lighter than air, hence it will rise up in air, making things float up in the air.


Why do helium balloons float better than just air balloons?

helium is less dense than air. :) so helium will float better than air


How do helium balloons float in the air?

Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.


How do balloons float in the air?

Balloons float in the air because they are filled with a gas that is lighter than the surrounding air. This gas, typically helium or hydrogen, creates buoyancy, causing the balloon to rise and float.
