Scientists Solve Water’s Hidden Secret at -81°F
Researchers at Stockholm University used x-ray lasers to find evidence of a hidden liquid-liquid critical point in supercooled water at -81°F (63°C). This discovery explains why ice floats and how liquid water expands as it cools below 39°F (4°C). Water’s behavior is unusual, unlike any other substance. It doesn’t shrink when cooled like most materials … Read more
