molecules of gas bouncing around inside the ballon
When air is blown into a balloon, the air molecules take up space inside the balloon and increase the pressure of the air, causing the balloon to expand. The increase in pressure inside the balloon pushes against its elastic walls, causing it to stretch and take up more space.
Yes, cold air contracts and takes up less space, causing the balloon to deflate.
Anything that takes up space has matter ... so YES ...
To prove that air takes up space without adding a manipulated variable, you can use a simple experiment where you place an inflated balloon inside a closed container. Close the container and observe that the balloon will prevent the container from being fully closed, demonstrating that the air inside the balloon (which is a part of the air in the container) is taking up space.
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.
Because air takes up space. When you attempt to blow up the balloon, you are adding air to the inside of it. But the air between the balloon and the bottle has no place to go. It will only contract so much.
It doesn't "come out" of the balloon or go "back in." The air inside the balloon is shrinking and expanding, which makes the balloon smaller when it's colder or bigger when it's warmer. This is because gases expand when heated and contracts when cooled.
Blow it into a balloon and you'll see it (= the balloon) grow.
When a balloon is cooled, the air inside it contracts and takes up less space, causing the balloon to shrink. This is because the volume of a gas decreases as its temperature decreases, following the ideal gas law.
If you prick the balloon in the "prick the balloon" science activity, the air inside the balloon will escape quickly, creating a popping sound. This demonstrates the concept of pressure and how air takes up space.
an inflated balloon has air in it so it takes up more space and matter is something that takes up more space so here by defining matter.
Blow up a balloon or inflate a tire.
