At cold temperatures, water has two different liquid phases, which become one at the critical point. The discovery could help ...

In physics, chilling out isn’t as simple as it seems. A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off in less time than it took a cooler ...

A new critical point in water has been discovered by Stockholm University physicists, explaining some of water’s strangest ...

New peer-reviewed experiments on supercooled water corroborate the transition between high- and low-density liquid states.

Scientists may have solved the long-standing mystery of why ice floats and why liquid ...

Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do ...
