# can water be compressed into a solid

At somewhat higher pressure at the same temp, it turns solid. Electric Field Change Freezing Temperature of Water? Can you take ice and eject it into a large/small enough vacuum space that it will turn into a gas? At quite a bit higher pressure, still at the same temp, it turns solid again. $P{\approx}1.55{\cdot}{10}^{12}\mathrm{Pa}$: Claim for water (so both hydrogen and oxygen together) going metallic: Based on density functional calculations we predict water ice to attain two new crystal structures with Pbca and Cmcm symmetry at 7.6 and 15.5 Mbar, respectively. Water freezes at the same temperature at sea level as at < 10 mbar and 100 bar? Imagine that in each side of the tube, you have very powerful pistons. Would the water turn into solid because the water molecules are so close to each other? The phase diagram of water is just bizarre. http://news.nationalgeographic.com/news/2007/05/070517-hot-planet_2.html. This is what is shown on a phase diagram, correct? But water is unusual in that ice is considerably less dense than liquid water, so extra space is needed to solidify the water, and that is less likely to happen the higher the pressure! Water can be converted to a gas (transpiration, steam from boiling, etc) and back to a liquid. Advice for getting a paper published as a highschooler. A new superionic phase was proposed with an approximate triple point of about 1000 K, 40 GPa with liquid (supercritical and ionized) water and ice-seven at high temperatures (~1500K) [1572]. If I'm reading that diagram correctly, it actually appears to be easier to turn ice into water at -20C using pressure than to turn water into ice at 20C using pressure. At pressures over about 5 TPa, it has been suggested that a phase splitting occurs with (the components of) H2O decomposing into a cubic Pa-3 H2O2 -formula phase and a hydrogen-rich phase, with metallization predicted at a higher pressure of just over 6 TPa [2114]. New York, If I try to push those molecules closer together, it would turn into a liquid. The answer is yes, You can compress water, or almost any material. The phase diagram of water is just bizarre. Would it turn into heat and escape the tube? What would happen? ... Around ${10}^{9}\mathrm{Pa}$, water's compressed into ice. Hence the Sandia research. What on earth happens at the "Solid/Liquid/Vapour triple point? Press question mark to learn the rest of the keyboard shortcuts, Exoplanets | Circumbinary Planets | Orbital Dynamics. Ask a science question, get a science answer. The chemical equilibrium will shift a bit. It's funny how the answer on chemistry site is more detailed than the answer here. If the water compressed, it wouldn't "push back" out of the straw. The experiment was done at the Sandia National Laboratories' huge Z machine, which generates temperatures hotter than the sun (setting a record here on Earth) and where researchers test what we know about those plain vanilla "phases" in textbooks: solid, liquid and gas. Density functional calculations [1709] indicate a pressure-induced initial displacement of the ice-ten atomic layers to give an orthorhombic Pbcm structure.

The state of ice at the very high pressures above ice X has only recently been reached experimentally. At some point, it probably collapses into a black hole, or something. Does this kind of ice instantly turn back to liquid if the pressure is removed or does it just melt like regular ice? Receive mail from us on behalf of our trusted partners or sponsors?
