The huge Z machine, uwe koch which generates uwe koch ms temperatures hotter than the sun, has turned water into ice in only a few nanoseconds. However, do not expect any of this ice conventional commercial uwe koch application: hot ms is the boiling point of water. The three phases of water that we know in our daily lives, ice cold, the liquid at room temperature and hot steam, are really only a small part of the repertoire of the states of water. When compressed, usually heated. But under extreme compression, it is easier for dense water entering your slida phase (ice) that while in his lquida more energy (plain water) phase. In the experiment with the Z machine at SNL (Sandia National Laboratories), uwe koch the volume of water is abruptly and discontinuously compressed. They may ask why this ice tablets instead of expanding, given the common experience that water ice expands and breaks uwe koch up a full bottle placed in a freezer. The answer is that only the "ordinary" ice, the water freezes, it expands. There are at least eleven other known forms of ice that occur under various temperatures and pressures. This work is a study of bsica science that helps us understand the behavior of materials under extreme conditions. But it can potentially have prctico value. uwe koch The work was undertaken partly because phase diagrams that predict the state of water at different uwe koch temperatures and pressures are not always correct. For example, a study using the Z DEMO machine a few months ago that astronomers' ideas about the state of water on the planet Neptune were probably incorrect. An unexpected result of the new experiment was solidificacin rpida water. Congelacin process, as is commonly seen, requires several seconds at best. The explicacina solidificacin so fast it seems that the compression rpida also produces a very rpida congelacin. Water samples were compressed at pressures uwe koch of 50,000 to 120,000 atmospheres in less than 100 nanoseconds. Under pressure of this order, the water seems to turn into ice VII, a phase of water discovered in the 1930s by Percy Bridgman, awarded a Nobel Prize. The compressed uwe koch water ice seems solidify in a few nanoseconds. Apparently, it is almost impossible to prevent the water from freezing at pressures beyond 70,000 atmospheres. For these tests, the Z machine cre magntica appropriate for compression conditions using for this twenty million amps of electricity.
