Once the air pressure inside the balloon is greater than the air pressure outside the surface it starts to fill. the higher the pressure inside the more the air acts against the inner rubber surface and the balloon gets harder. an empty balloon has the same air pressure inside and outside. Once you push any air in therefore you are starting to raise the air pressure inside.

What else can I help you with?
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.
When you blow into a ballon what makes it get bigger?
Blowing air into a balloon increases the pressure inside the balloon, causing it to expand. The balloon stretches in response to the increased air molecules inside it, causing it to inflate and become larger.
Why does a balloon expand when you blow it?
You are pushing more air into the balloon.
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.
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.
Why does a balloon expand when you blow in it?
When you blow air into a balloon, you are increasing the pressure inside the balloon. This increase in pressure causes the rubber of the balloon to stretch and expand, filling up with the air you are blowing in. The elastic nature of the rubber allows the balloon to expand and hold the air inside it.
