helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!
yea i kenisha am smart
Helium is less dense than air, therefore a helium-filled balloon will float in air.
Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).
I dont fully understand the question, but helium is alot lighter than air, and the elastic that makes up the balloon is very light. So helium in air is like air in water, the helium in the balloon forces itself up as high as it will go.
Helium molecules are less dense then air molecules causing the helium in a balloon to rise. Sorry, just noticed you said hot air balloons in which case I have no idea but I would assume there is no helium in a hot air balloon as it uses hot air to float in the sky

Generally, it is helium. Hydrogen could work, but that would be dangerous.
Helium
hot air balloons
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
helium is generally filled in helium balloons
Helium is an inert gas."They fill Helium in the balloons", father explains his child.
either for balloons, or whip it's.
10000000 helium balloons
helium balloons and make your voice sound weird
no. If it was, we would have oxygen balloons instead of helium balloons.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.

No. Helium is not radioactive.
Yes, helium weather balloons are commonly used.
Yes, balloons filled with helium will be buoyant in air
