Better check on that again, helium is lighter than air and the specific gravity of air is approximately 1.3 milligrams per cubic centimeter. Water weighs much more than air, 1 gram per cubic centimeter.
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.
It depends on what the balloon is filled with.A balloon may float if it is filled with any gas that is less dense than air: hydrogen, helium, even pure nitrogen gas. However, the weight of the balloon will determine whether it can be lifted by the difference in density. So the most effective lifting gases are hydrogen and helium. Helium is used because it is nonflammable and noncorrosive. Early German dirigibles (zeppelins) were filled with hydrogen, and some caught fire, notably the Hindenburg in 1937.Larger balloons can be lifted by hot air, which is less dense than cooler air. If the air cools again, it will no longer provide lift.
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
The molecular mass of helium is 4. The molecular mass of nitrogen, the most common component of air, is 28. Since all gases take up about the same amount of space per mole at a given temperature and pressure, helium is about 7 times less dense than nitrogen, and oxygen, the second most common constituent of dry air, is even more dense than nitrogen.
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
Helium is less dense than air
Yes, it will It's actually better to use nitrogen in balloons because it floats better than helium.
The composition of air is roughly 78% nitrogen and the remainder except a negligable amount of hydrogen is more dense than nitrogen. Therefore a balloon filled with nitrogen will be less dense then the surrounding air and thus will rise. The balloon will probaly not rise, as there is insufficient lift to overcome the weight of the balloon fabric. Are you sure you don't mean Helium, or Hydrogen?

Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.

Because air is not as dense as helium filed gallons so they won't float
