Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?

Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.

Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases
Why does helium rise and regular air sink?
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
What happens when a helium-filled balloon is released and rises into the atmosphere?
It pops
How does a balloon rise against gravity?
A balloon is filled with helium, which is less dense than the air around us. Because of this, it is able to float. But, over time, the helium leaves the balloon making it fall again.
Which has more buoyant force of atmospheric pressure an elephant or a small helium filled balloon?
Elephant. :)
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
Why is that a big balloon filled with the helium floats?
Helium is lighter than air. hence helium balloon will float in air.
What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
Is a hot air balloon filled with helium?
no its filled with hot air from a fire that is lit underneath the balloon.
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 is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
Is balloons filled with helium a chemical change?
A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
Can a blimp filled with helium float in the air?
Yes, it can. Just as helium balloon will.
What is the average cost of a helium balloon?
Average cost of 1 regular size helium balloon: $1
Will helium balloon pop on airplane?
On modern airplanes no, because the cabin is pressurised to the same atmospheric pressure as on the ground. If the balloon was on the outside of the plane, and the atmospheric pressure at that altitude were low enough, then yes, the balloon would pop.
