Garrettguy457 Posted January 19, 2009 Share Posted January 19, 2009 Can a liquid, gas, or plasma be compressed into a solid if u keep a constant temeperature. I realize the relationship between temp/pressure which is why I am asking this question with the added "constant temperature". Thanks Link to comment Share on other sites More sharing options...
iNow Posted January 19, 2009 Share Posted January 19, 2009 I'd think not, as compression will increase temperature. As for maintaining constant temperature while pressure increases... well... you can do just about anything when you suspend the laws of physics.

Klaynos Posted January 19, 2009 Share Posted January 19, 2009 Have a look at the phase diagram for the material you are interested in and draw a line of constant temperature. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted January 19, 2009 Share Posted January 19, 2009 The answer is yes, but it would require an ungodly amount of pressure. It is much easier to do with gases because they are easily compressible, but most liquids are nearly incompressible. The solid core of the earth is the most famous example of liquid compressed into a solid. Link to comment Share on other sites More sharing options...
DrP Posted January 19, 2009 Share Posted January 19, 2009 Can a liquid, gas, or plasma be compressed into a solid if u keep a constant temeperature. If you compress it - the temperature will increase - so to keep the temperture constant, you need to remove energy from the system by cooling it in some way - so yes - if you increase the pressure of a liquid whilst providing a cooling effect to keep the temperature constant, then the liquid will freeze (depending on where you are on the phase diagram for that liquid as Klaynos said).

CaptainPanic Posted January 21, 2009 Share Posted January 21, 2009 Yes. It is possible, although perhaps we're not able to: 1. always achieve such pressure 2. recognize the solid that appears... since perhaps molecules that existed before also react with each other and form some weird compounds that are more compact. I found this an interesting read. I'm not sure it treated the constant temperature aspect... but it's high temperature, not low... so it might be good enough for this discussion? http://www.sciencedaily.com/releases/2008/09/080903134318.htm Link to comment Share on other sites More sharing options...
