Helium rises because it is less dense than the air. If it is less dense then it will rise above the air until it meets a gas lighter than it. There are other gases lighter than air. You should experiment with other gases inside balloons.
Less dense, or 'lighter than Air'.
A one liter balloon filled with Helium and placed on a weigh scale will weigh less than the same balloon filled with air.

∙ 14y agoThe density of helium is 0.1786 g/L
The density of air is about 1.2929 g/L (It depends on where you are)
The heaviest substance always settles on the bottom, making the lighter one rise.
AnswerHelium is a gas that is lighter than air.Just like a boat displaces water and floats so does Helium in air.
The balloon is the Boat (submarine would be wore accurate but we started with boat)

∙ 13y agoEveryone says that helium is lighter (less dense) than the air we breathe and this is why the helium balloon rises. A more thorough explanation is this: If you look at the Periodic Table, you'll see that helium has a mass (sort of 'weight') of 4 amu's. The air around us is made of nitrogen and oxygen primarily. Now the mass of nitrogen and oxygen are 14 and 16 amu's, respectively. So even though the balloon doesn't seem lighter than the air around it, it is lighter (less dense is a better word though) and so it rises.

∙ 12y agoHelium is lighter than air, so it rises above air. If a balloon (or any other object for that matter) was full of helium, it would rise above air.
The density of helium gas is less than that of air.

∙ 11y agohelium's density is lower than that of air (which is 79% Nitrogen, 20% Oxygen), do it floats like a piece of wood in water.
Wiki User
∙ 11y agoHeilum combined with the light material of the balloon make it as light as air, making it float.
Helium is lighter than nitrogen and oxygen, therefore making it rise.

∙ 14y agobecause helium gas is lighter than air, so it floats above it

Can you make a balloon fly without hot air or helium?
Yes: Try hydrogen - it worked for the Hindenburg
How do you make a balloon filled with air fly straight?
Put a straw in the end of it and blow into the balloon. That should make it fly straight although make sure you don't use helium and make sure there is as little of wind around as possible. From Matthew
How high do helium balloons fly before they pop?
Depends on the type of rubber and amount of helium in balloon
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
Is inside balloon solid liquid or a gas?
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
What do you put in a balloon to make it fly?
Helium
Does helium help the balloon fly?
Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
Which balloon would fly higher the one with helium or the one with air?
The balloon with helium.
What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
How do balloon fly?
Balloons are filled with helium. Helium is a gas that can make light objects float, or make your voice all squeaky. So if you want to pee your pants laughing, go cut a small hole in a balloon and suck the helium out and then speak.

How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Why do balloons fly with helium and not with normal human oxygen?
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
Why after 24 hours helium balloon won't fly what is happening with the helium?
The helium is escaping through the small holes of the porous balloon. Plastic does have microscopic holes in it and Helium is as small as Hydrogen gas. (Hydrogen gas is diatomic.)
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
