Hydrogen is lighter than air, so the force of gravity is overcome by the force of the heavier air pushing on the balloon. Same as why bubbles float to the top of water. When balloon is filled with air there is no competing force so gravity takes over and pulls the balloon down.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
If you want the balloons to float, you would probably use helium.
Helium gas is found in balloons that rise to the ceiling. This gas is less dense than air, causing the balloon to float upward.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
Helium is lighter than air, hence balloons filled with helium will float and rise up.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
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.
Helium is the most common gas used to inflate balloons because it is lighter than air. This allows the balloon to float and rise when filled with helium.
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight 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.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.

So that the balloons float
