So that the balloons float


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.

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.


Why do balloons only float with helium?

Balloons filled with helium float because helium is lighter than the surrounding air, creating a lifting force. This is known as buoyancy. Regular air-filled balloons are denser than the surrounding air and do not float.


If you wanted to make a balloon float in the air which gas should you use to fill the balloon?

Helium gas is lighter than air and hence balloons filled with helium will float in air.


Why do big balloons with helium gas floats and buoyed up?

Helium is lighter than air, hence balloons filled with helium will float and rise up.


Why do balloons float up to the sky?

The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.


What is added to balloons and hot air balloons?

Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
