So if you apply enough pressure ot a liquid...

[RESmonkey]

Except for water and other liquids that are more dense than their solids, can you, like, compress a liquid into a solid?

 

[BrownTown]

Like you said, would have to look at phase diagrams, but its alot harder than gas to liquids.

how does that help? It only applies to ideal gases

I don't believe so... liquids are not able to be compressed. In a liquid all the molecues are 'together' but not arranged in a crystal, I don't think pressure would change that, not the way it would in a gas. Then again I'm no scientist, so someone may correct me.

Oh yea, and solids are not always more dense then a liquid, take water ice for example. The solid is actually less dense then the liquid form of the chemical, so if you could compress it more that'd do the opposite.

So wait a sec, I've wondered this, if you apply enough pressure to liquid water it has to do SOMETHING. Something's gotta give, physically speaking. Is water really completely, utterly incompressable?

You can compress it all you want, it's still water.

Go to the bottom of the marianas (sp?) trench - yep, still water.

If you compress a volume of water into a smaller space, it's by definition more dense. Hence, it compresses. People here are saying you cannot compress water. If you're saying it will get more dense, that's compression, and therefore the people saying it can't compress are wrong. That's fine, I was just curious.

The dotted green line represents what happens with water and antimony (Sb).

Um, well, liquids are a tiny, miniscule bit compressible, but for the most part, no. That's the whole basis for hydraulics. You push on a liquid, it pushes on the next object with the same force (or more or less force, depending how the valve is set up).

Yes with enough pressure you can turn water into a solid AKA "HOT ICE"

Well sure, you can compress water on a black hole, but it is not able to be compressed under 'normal' circumstances.

We're not talking about water. Water is a bit different, because ice is less dense than water. I'm talking about any other liquid. Say I have liquid CO2. Can I compress the liquid to a point where it will just turn into a solid?

So far I figured out that it depends on the substance (have to look at phase chart). TY above posters.

At the right tempurature. Phase diagrams have been developed for some compounds and elements.

i was going to comment on this. i remember seeing a show on the planet. pretty neat stuff

 

[BrownTown]

The answer is YES for many substances it will work, however it will take ALOT of pressure. Also that whole "incompressible liquid" stuff is an ideal situation not reality.

 

[LordMorpheus]

you can compress ice into water.

Simple experiement:

block of ice. suspend a weight from either end of a thin wire, with the wire laying across the ice.

put the temperature slightly below freezing.


The wire will slowly move down into the ice block, as the pressure the wire puts on the ice below it causes it to melt, but then the water will re-freeze above the wire.

 

[FoBoT]

yeah, it depends
