What happens to water at just above absolute zero degrees?

Click For Summary

Discussion Overview

The discussion centers around the behavior of water at temperatures just above absolute zero, particularly focusing on its solid state and the formation of crystals versus glasslike structures. Participants explore the implications of rapid cooling and the nature of glass as a solid.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants inquire whether water can be solid without forming crystals at temperatures just above absolute zero.
  • It is proposed that extremely rapid cooling or vapor deposition below approximately 140 K can result in a glasslike solid form of water.
  • There is a question raised about the classification of glass as a solid versus an extremely viscous liquid, with references to historical artifacts suggesting potential flow.
  • Some participants assert that glass is an amorphous solid and challenge the idea of glass "flowing," requesting evidence for such claims.

Areas of Agreement / Disagreement

Participants express differing views on the nature of glass and its classification, with no consensus reached regarding the evidence of glass flowing or the characteristics of water at low temperatures.

Contextual Notes

The discussion includes references to specific temperature thresholds and the lack of consensus on definitions related to glass and its properties, as well as the implications of rapid cooling on water's state.

I know that water forms different kinds of crystals in different kind of temperatures but is there any temperature where water is solid but does not form crystals for example just above absolute zero degrees, what kind of crystals does it form?

Extremely rapid cooling, or vapour disposition at temperatures below ~140 K can form a glasslike solid.

Well answered. But that raises another question. Is glass a solid or just an extremely viscous liquid. Glass objects removed from Egyptian tombs show evidence of "flowing".

You can say yes because it does not have a normal melting point.

Some people also refer to it as a amorphous solid. There is no real consensus to my understanding.
 
Glass is an amorphous solid. As far as I know, there is no actual evidence of glass "flowing", just anecdotes which are poorly supported. If you have any actual references for the glass objects from egyptian tombs "flowing", I would love to see them, but all of the actual information that I have seen indicates the contrary.
