If the wind stays down, these discs branch out into tree-like shapes that expand across the surface of the water until the whole cove or pond is covered by a thin skim. Once the lake has frozen over, the progress of ice formation slows.
WebbThis paper analyses the phenomenon in terms of quantitative measurements of the hydration interaction among membranes or macromolecules at freezing temperatures. These results are related to analogous measurements in which osmotic stress or mechanical compression is used to equilibrate water of hydration with a bulk phase. Webbför 11 timmar sedan · It was already known that, at the nanoscale, water can remain mobile within channels at temperatures below 0°C. However, this study showed for the first time that such channels can also allow the...

If the water is not pure, particles get in the way of molecules linking up so water will not freeze as quickly. When temperatures are low enough and the molecules can link up and not break apart, then they freeze.
