It can't just disappear can it?

I found this question on the internet, and I was having trouble trying to solve it on my own. I'm sure it cannot just disappear, but I'm curious what happens when it does get compressed compressed compressed..

Would it not become harder on the surface perhaps less penetrable sine there would be less air wouldn't it? Wouldn't compression force air from around and inside the water changing it! I am not sure, but Hope someone really knows the answer!

Hmm.. How about this..

Since water is H2O.. If it is compressed hard enough. The Oxygen and Hydrogen pop out? Like, separated because of the pressure. Only have a guess at it though.

i think it would turn to ice...but possibly am wrong.

Ice? Explain please, I think you may be on the right track.

[Karen W.]

Hummmm thats is interesting..

WHOOPS MORNING PAUL!! LOL

WHOOPS MORNING PAUL!! LOL

Lol yah, HI Paul as well [] Hang on, I'll bring you your tea and some waffles []

Me asked this question a while ago..if the search facility worked I could found it...but me thinks it would get hotter. Hot enough to make a nice cup of tea.(though me drinks coffee,,but I said tea cos that sounds more quaint)

[Karen W.]

So hotter instead of colder.. why?

[another_someone]

This question can have quite a few answers, depending on variables.

Firstly, while most liquids can shrink by becoming sold, water is one of the exceptions in that crystalline ice takes more space than water at the same temperature.  It is possible you may form amorphous ice.

If you squeeze hard enough (harder than would be possible with anything on Earth), the electrons would fuse into the nucleus of the atoms, creating neutons (this is what happens in a neutron star - but under immense gravitational force).

Increase the pressure even harder, and you will form your own black hole (although a very small black hole would be unstable).

Ah, my life saver George again! Thanks. I can see that your IQ is 150. []

And Neil.. According to a Podcast I heard on this site..

You need to scream for 8 years without stopping to produce enough heat to warm a cup of coffee.. []

Any substance will get hotter when placed under pressure, and if it changes phase (e.g. from liquid to solid) it will usually generate even more heat from the latent heat of fusion.

But making water into a solid (ice).. Don't you cool it, instead of heat it?

[neilep]

As a firm believer in empirical study I am squeezing some water between my thumb and forefinger as hard as I can !!....it is getting warm...in fact it's evaporated !!...QED

[Seany (OP)]

Lol. I love it when you say the "As a firm believer in empirical study.." Its hillarious. []

I think you've turned 8.5 again. []

OY !!...me um well klevur !!...me beat a haddock in um intelligence test...it was um close call !..methinks me was lucky that haddock was still frozen in the freezer else I would have come second !!.....let this be a lesson to ewe that Haddocks are like...well klevur !!

[Seany (OP)]

Mmm.. Yes. This is why you talk in a baby language. I see []

When water turns to ice, it gives off heat.

If you cause heat to be drawn away from the water, then you force it to give off the heat as you draw it away.  If you don't draw it away, it just gets hotter.

One of the things you will notice as you cool water (at constant pressure), is that as you draw energy from the water, it will (not surprisingly) get cooler; but as the water starts to freeze, you will keep drawing energy (heat) away from the water, but it is not getting colder; and only when all the water has turned to ice will the ice now start to get colder again as you draw energy away from it.

[Seany (OP)]

Yes. It gives off heat because the particles become more closer together and lose energy. But still isnt the "thing" itself, cold? Not the thing which is given off.
