Because air is not as dense as helium filed gallons so they won't float
bcoz helium is lighter than 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.
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.
Helium is lighter than air. so balloons filled with helium will float in air
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
Because it is a safe gas that is less dense than air, thus balloons float in air
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Helium is lighter than air.
Balloons filled with it float in air
Because helium is lighter than 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.
They are filled with hot air. The hot air raises and take the balloon with it
