As we have already discussed water’s reaction to the cold vacuum, the time for exploring its properties once it is based on a an extremely high pressure. Because that the services of our exploration, let’s build a perfect equilibrium device with a container—let’s make it through Uru or an indestructible metal from your own fictional universe—that is just indestructible. Let’s rig it v a coolant assembly to preserve the temperature the exact same throughout the compression process.
You are watching: How much can water be compressed
Let the pressure rise
The approximate ambient temperature would certainly be 303.15K and also the atmospheric press would be 100 kPa. As soon as you keep this temperature and also increase the push in the indestructible container, water changes from a liquid phase come a hard phase as soon as the pressure rises over 1GPa. This is since the molecule are currently tightly pack under the pressure and also an obvious change would it is in to the solid ice, however with a various temperature (room temperature in our case, v the coolant device removing the heat) and crystalline structure, unlike the regular ice. The following phase diagram of water could assist you understand this better.

Upon increasing the push further, the crystal structure of the ice will readjust from ice vi to ice cream VII and ice X to ice XI. Currently you understand that there are of course different forms that ices present in this universe. Unfortunately, these develops of ices have the right to only be seen in the research study labs and not inside her freezer (Duh!). In instance you space pondering what’s so various in these ices, it is their crystal structure.
I want an ext pressure
Sticking through our theoretical pursuit, once we boost the pressure past 1Tpa, the crystal structure could turn right into a metallic structure as speculated in a record here. This study even claims that there space two much more crystal structures besides the currently phases. ~ above the various other hand, there is also a opportunity that the molecule of the ice cream XI will certainly dissociate right into hydrogen and oxygen atoms. There space still number of possibilities favor the formation of hydronium, but let us focus on part highly possible hypothetical scenarios.
Let’s stop the cooling and make that adiabatic
So far, we have actually been cooling down all the heat produced by the water, as the work-related is excellent on it v a coolant. As soon as we remove our coolant assembly about the container, the energy in the system boosts the temperature of the solid ice. But still, us will have the very same ‘hot ice’ desperately existing together plasma (degenerate matterDegenerate MatterDegenerate matter is matter which has actually such extremely high thickness that the dominant contribution to its push is attributable come the Pauli exemption principle - Source: princeton.edu. A degenerate issue is the sort of matter uncovered inside the main point of a dense star.). And when we torment the device with more pressure—good enough to conquer the coulomb pressures of the nuclei—the hydrogen atoms will fuse to type helium, which would eventually finish up in developing a small neutron star or also a selfhood if you are the god of pressure.
Is water compressible or incompressible?
Of course, the water, like any type of other matter is compressible. But prior to you could throw in a debatable declare of incompressible fluids right into our conversation box below, you might have come brush up about the term bulk modulus. In general, it’s defined as how much a liquid or a solid have the right to resist the pressure used to compress that from every the directions. As water has actually a mass modulus that 2.2×109 Pa, water is compressible.

But the is not almost compressible for the least. In order to compress water, you would require so much pressure. Even at the deepest areas of ours oceans, the thickness of water is only a little greater than that of the water in ~ the surface, and also the compression is around around 1.8% only. So the bottom heat is once you compress the water, the turns into solid, the density increases apparently and also it exists in one of the 16—excluding the one in your freezer—known crystalline phases that the ice. As of 2015, us only understand that over there are only a few high-pressure ice cream phases that water and the rest will it is in unlocked very soon in the future, if we could attain pressures past the present limits.
