helium is lighter that air so rises above the air. similar to oil rising above water.

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.
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 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 are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)
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.
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.
Gas that is less dense than air?
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
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.

How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
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.
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 are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)
Why is that a big balloon filled with the helium floats?
Helium is lighter than air. hence helium balloon will float in air.
Is a hot air balloon filled with helium?
no its filled with hot air from a fire that is lit underneath the balloon.
