It's the 2nd lightest element so is less dense in air making it float. The 1st lightest element is hydrogen which is flammable which you wouldn't like at a 5 year old's birthday party.

How many gases are there for balloons?

There are several gases commonly used for filling balloons, with the most popular being helium and air. Helium is lighter than air, allowing balloons to float, while air is typically used for ground decorations. Other gases like hydrogen can also be used, but due to its flammability, it is less common. In total, the primary gases for balloons are helium, air, and sometimes hydrogen, along with other specialty gases for specific effects.


Which gas is used to fill the balloons?

Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.


What type of gas is used inside foil balloons?

Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.


Why is helium suitable for filling party balloons?

Helium is lighter than air, so balloons filled with helium will float. It is also non-flammable and safe to use. Additionally, helium does not react with other chemicals, making it a popular choice for filling balloons.


Why do helium balloons float better than just air balloons?

helium is less dense than air. :) so helium will float better than air

Which balloon can float the longest?

Helium balloons can float the longest because helium is lighter than air, providing buoyancy. Other gases like hydrogen can also make balloons float, but helium is safer as it is non-flammable.


Can you inflate a balloon without helium?

You can use air instead of helium, but it will not rise. The reason helium balloons rise is because helium is lighter than air. I am sure other gases can be used also.


What gases can blow up a balloon?

Any gas will inflate the balloon. It simply needs to be introduced into the balloon at a pressure greater than that of the surrounding atmosphere (plus some additional allowance for the pressure required, if any, to stretch the balloon material).


Why helium is better than hydrogen for balloons?

because helium does not mix with other elements

What property of helim makes it good for filling balloons?

It's Helium. Helium is lighter than the air around us, so it tries to go upward. This makes the balloon float. The other gas lighter than air catches fire easily, so they don't use that. That's the basic definition. Comment if you want the technical one.


If Air helium in balloons oxygen in a tank it is called?

If air is helium in balloons and oxygen is in a tank, it can be referred to as a gas mixture. Helium-filled balloons typically contain helium gas, which is lighter than air, allowing them to float. In contrast, oxygen in a tank is stored as a compressed gas, often used for medical or industrial purposes. Both helium and oxygen are important gases with distinct properties and applications.


Is balloons filled with hydrogen and oxygen?

If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
