Subcooled water is actually a set of two different liquids in one. Such a discovery was made by scientists from the United States, who properly studied liquid water at temperatures below freezing point.
Water, despite its prevalence, still contains some puzzles, to explain which the scientists of different specialties are just choosing. Some researchers even call water the most mysterious substance on our planet.
You bet, because water has a number of strange things. For example, when it freezes, it expands rather than shrinks like other liquids, and its density falls. That is why the ice floats on the water surface, not sinking. Plus, water has a huge surface tension coefficient, it is able to dissolve most substances, and it has a fairly high boiling point. All these qualities have made water the basis of earthly life.
One of the interesting properties of water is its “reluctant” freezing. If crystallization centers (solid particles) are removed from water, it will resist to the last “resist” the transition to a solid state during cooling. The subcooled water has not yet been sufficiently studied, so the staff of the Pacific Northwest National Laboratory decided to fill this gap in scientific knowledge. The scientists conducted experiments with thin ice film and laser, which revealed that subcooled water condenses into a dense liquid that exists together with ordinary liquid water. That is, at very low temperatures, subcooled water exists in two structural forms at once.
