When a balloon is "blown up" with your mouth, you are just passing "air" which is mostly Nitrogen, Oxygen and Carbon Dioxide. When a balloon is blown up so that it can float, then Helium gas is used. Helium gas is lighter than air, allowing the balloon to float. Other gases, such as Hydrogen are also lighter than air, however they are either dangerous or expensive to produce. For example, hydrogen is explosive. Helium is both inexpensive, and inert.

How can you blow air in or out to inflate a balloon?
To inflate a balloon, you can blow air into it by using your lungs to push air out of your mouth and into the balloon. Alternatively, you can use a pump to push air into the balloon.
Can you blow a balloon up with air?
Yes you have to but here is a tip: if you want the sturdiest balloon blow it up halfway and then insert pancakes before you blow it up anymore
What happens to the particles of air when you blow into a balloon?
When you blow into a balloon, the particles of air you exhale are compressed and forced into the balloon. This increases the air pressure inside the balloon, causing it to expand and inflate.
What do you call the part when you blow into it on a balloon?
It's called the "mouthpiece" of a balloon, where you blow air into to inflate it.
Why does a balloon expand when you blow it?
You are pushing more air into the balloon.
When you blew a birthday balloon what gas will it be inside the balloon?
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
What is an example of air expanding?
An example of air expanding is when you blow up a balloon. The air inside the balloon takes up more space as you blow more air into it, causing the balloon to inflate and expand.
What air is used to blow a balloon with the mouth?
Carbon dioxide, the air we have in us that we breath out. Carbon dioxide doesn't make the balloon float in the air, while Helium does.
When air heats in a bottle you can a balloon?
The air alone is not able to blow up a balloon. When air in the bottle is heated with a balloon on top of it, the air expands due to the heat and moves and finds more space. This in turn will blow up the balloon.
Why ballon expands as you blow into it?
When you blow air into a balloon, the pressure of the air you are adding is higher than the surrounding air pressure inside the balloon. This increase in pressure causes the rubber of the balloon to stretch and expand. As you continue to blow more air, the balloon grows in size until the pressure inside the balloon equalizes with the pressure outside.
Why does a balloon burst if you continue to blow air in it?
Blowing air into a balloon increases the pressure and stretches the balloon material. If you blow too much air, the pressure inside the balloon exceeds the elastic limit of the material, causing it to burst.
Is a balloon a solid?
Balloon is a solid because it has a definite shape when we blow or don't blow air into it.
