Umm...I believe it is air! If it were helium there would.....forget it, I'm not going there....
Different footballs are used for kickoffs, field goals and punts in the NFL. A sideline employee is responsible for switching the balls out before each kick.
No, soccer balls are not filled with helium and are not used in any sports competitions.
No, professional soccer balls are not filled with helium and are not used in official matches or competitions. They are typically filled with air or a combination of air and other gases.
No, professional soccer balls are not filled with helium and are not used in official soccer matches. They are typically filled with air or a mixture of air and other gases.
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Close to impossible. Helium is about as inert as it gets. The only way there have been any reactions with carbon was to create miniscule geodesic spheres and force the helium atoms inside. These are commonly referred to as "bucky balls" after Buckminster Fuller who used geodesics in architecture, and more properly as buckminsterfullerene. I have never heard of any reaction at all with potassium.
Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.
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.
Helium gas is used inside balloons to make them float. Helium is lighter than air, so it creates a buoyant force that causes the balloon to rise in the atmosphere.
Helium is commonly used to inflate balloons as it is lighter than air. This causes the balloon to rise as the helium inside is less dense than the surrounding air.
mostly helium is used in balloons
