Yes, a balloon shows that air can be compressed. The pressure in the balloon is higher than the pressure outside the balloon. The ideal gas law is
PV = nRT
where:
P = pressure
V = volume
n = the number of moles of gas (the amount of gas)
R = the ideal gas constant
T = temperature
So for the given volume of the balloon, and at a set temperature, if the pressure goes up, the amount of gas (the number of moles) must also go up. That means that the gas has been compressed.

What has compressed air in it?
a tire has compressed air, vacuum, balloon, inhaler and so much more can u find 15 in your house that have compressed air
What gas put in a balloon would make it fall?
Any gas that is more dense than air.Answer:It is a bit more complex than that - an air filled balloon would still fall because air has the density of air. In a normal inflated balloon the air in the balloon is compressed and has a density more than uncompressed air. If the "balloon" were a plastic bag wiith no air pressure above the pressure of the surrounding air, the balloon would still fall as the combined (average) density of the balloon/bag system is greater than the surrounding air. Even if the balloon were filled with a gas with a lower specific gravity than air the balloon wll fall if the compressed gas density excedes that of the surrounding air or if the combined (average) density of the balloon/bag or balloon system is greater than the surrounding air.
How do you pierce a needle into the balloon and not to break the balloon?
...by pinching the balloon between your thumb and index finger and inserting the needle between the compressed rubber of the balloon at that point without letting go of the compressed balloon until you release the needle from the balloon.
How do you make an experiment to show that air occupies space?
The easiest way to demonstrate the volume of air is with a balloon. When it is inflated, the air inside is occupying space. Deflate the balloon - it shrinks in the absence of air.
Why does water prevent a balloon from popping?
The 'popping' sound of a balloon disintegrating is made by the sudden expansion of air when the skin is damaged. The compressed air within is then able to escape. One interesting variant of your 'water' experiment, is to stick a bit of cellulose tape to the balloon, and then you'll find that you may puncture the balloon; through the tape; without it popping! It will eventually deflate however.
What is compressed air propullsion?
The easiest way to describe compressed air propulsion: Blow air into a ballon (compress the air) then release the balloon. The balloon will take off (propulsion) due to the compressed air within.

How can you do an experiment on how air makes force when air is compressed?
Begin by placing a semi inflated balloon on the end of an empty soda plastic soda bottle. Then squeeze the bottle and watch the balloon inflate slightly, this demonstrates when the air is compressed inside the soda bottle it creates pressure to fill the balloon and push it up. This is not only a great way to show this property of air to somebody, its cheap for a small class experiment.

How can you use expanded in a sentence?
When connected to a source of compressed air, the balloon expanded until it burst.

Why air is compressed?
Because there is so much molecules that it can not get anymore in it like a balloon when u tie it u can squish it and it is compressed

What happens on a molecular level when a latex balloon is filled with 3L of air?
Because the balloon gets stretched when it is inflated and it is trying to contract again it pushes inwards. The molecules in the air get compressed slightly because of the confined space, meaning that the density of the air in the balloon increases. The molecules move closer together = more Energy = slightly warmer.

What is the study of compressed air?
compressed air science
Which categories is usage of compressed air and gas divided into?
The three major categories of usage for compressed air and gas are: compressed air and gas for process services, compressed air for power, and compressed air for general industrial applications.
