Helium is less dense than air because it has a lower density. This is why helium balloons can float in the air.

Gas that is less dense than air?
Helium is a gas that is less dense than air. It is often used to fill balloons because it causes them to float.
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
Is helium less dense than air?
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.
Why does a helium filled balloon rise in relation to its density?
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.
Are noble gases less dense than air?
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
What is more dense helium gas or air?
air is more dense than helium
Why a balloon filled with helium floats in air?
Helium is less dense than air
What floats on air?
helium balloon because helium is less dense than air
What substances is less dense than air?
Plasma.
Why do helium-filled ballons raise in air?
Because helium is less dense than air.
Gas that is less dense than air?
Helium is a gas that is less dense than air. It is often used to fill balloons because it causes them to float.
What has more lift hot air or helium?
Helium has more lift than hot air because it is less dense and therefore creates more buoyancy. Hot air balloons are inflated with hot air to make them less dense than the surrounding air, but they still provide less lift compared to a balloon filled with helium.
Is helium a less dense item?
Yes. Helium is lighter than air.
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
Why does a baloon filled with helium float in air but the baloon filled with carbandioxide sink?
Because Helium is less dense than air, and CO2, I assume is more dense
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
