Can gases be compressed?

Question

If gases can be compressed, can solids and liquids?? Also what does compressed mean?? Thank you!!

Answer 1

Compressed means that by applying a pressure (force per unit area) or a Force its volume deceases. Liquid can generally be assumed to be incompressible as there volumes do not alter that much, whilst for solids it is generally taken that there volume do not alter at all when pressure is applied.

Answer 2

Yes. Do you know Boyles Law? Pressure, Temperature and Volume are all inter-related. If you compress a gas and in so doing reduce the volume it takes, its temperature rises. That is the main principle of how air conditioning works (and also the amount of latent heat absorbed or liberated when the gas changes to a liquid and vice-versa). How do the tyres of your car say up? Simply by compressing the air in the tyre to around 2 bar, or 28 pounds per square inch. Only a low pressure, but compressed nevertheless.
Same applies to liquids, though of course it is a little harder to compress them, and also solids, which are usually heated to soften them before they are compressed.
Compressed means containing a given quantity of a substance into a smaller volume than originally.

Hope this helps.

Answer 3

Gases can definitely be compressed to very high pressures.
Some solids are compressible to some extent.
Liquids are virtually incompressible.

To compress means to 'squeeze' into a smaller volume.

Answer 4

Gases can be compressed which means 'made into a smaller volume'. Solids and liquids cannot

Answer 5

compressed is squashed so it is smaller. Gases definitely can be compressed. You can work out the liquids and solids bit.

Answer 6

Anything can be compressed with enough force. That means that the volume of a given mass is decreased through the application of a force or (pressure) which is force per unit area. Some things compress easier than others. Water compresses so little that it is regarded as incompressible.

Answer 7

compressed means to squash! squish! squishify! sqaushify! you get the point lol solids CANNOT be compressed because if you get a syringe and put a solid in there and squeeze down the thingy its gonna get stuck cause the particles in the solid are really tight together and have these bonds connecting them together and those bonds are really close holding each particle together really close to each other. if you put in a liquid or a gas in the syringe and squish it the liquid/gas comes spurting out because liquid/gas particles have further away/no bonds holding together the particles so the particles can change to the shape of the container its put in and because of that (no not finished just yet!!) they get squished out of the syringe! hope that helps ;) lol

Answer 8

yes of corse they can, liquids can be a bit but not solids, compressed meens to be pressed down, it because in a gas the particles are further apart and have space to be compressed, in a liquid they are closer together and in a solid they are all together which makes it, well, a solid!

Answer 9

yes. Anything can be compressed. the reason spray paint
..
works, is that they put paint and propellant gas into a little
..
bottle until they have to try to force more in. Because the
..
pressure inside the bottle is greater than the air pressure out
..
side of it, the paint tries to escape as fast as it can.
..
This is an example of COMPRESSION.

Answer 10

Gasses can be compresses because their particles are very loosely packed.
Liquids can be compressed, but not as much, because their particles are packed tighter together.
Solids can't be compressed because the particles are very tightly packed together.
Compressed means reducing the volume and increasing the pressure.
