Freezing Temperature for Waterの概要と注目ポイントを徹底的にカバーしました。

Here’s a brain-bender: you can melt ice with pressure. Seriously. A regular ice cube has a liquidy skin from the pressure of the air and the container alone. If you squeeze an ice cube (not with your fingers, you monster, with a hydraulic press), you raise its freezing point. At enough pressure, ice becomes a substance called Ice III or Ice VI (yes, there are at least eighteen different kinds of ice), which are denser and structurally bizarre. This is how ice skates work: the narrow blade applies immense pressure to the ice, creating a thin layer of liquid water to glide on. You aren’t skating on ice; you’re skating on a microscopic film of lubricating water that instantly refreezes after you pass.
