No, just air.
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.
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.
No, helium is not used in medicine.
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.
either for balloons, or whip it's.
mostly helium is used in balloons
How Helium is used: It is used to blow up balloons.
that can helium do to you
Helium can be used in refrigerators, but this application is expensive, not commercial.
