Dense Water Stays Liquid Well Below Freezing Point
In experiments at SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory, scientists observed a surprisingly dense form of water that remained liquid well beyond its typical freezing point.
Researchers applied a super-thin coating of water – no deeper than a few molecules – to the surface of a barium fluoride crystal. This surface was expected to stimulate ice formation, but even when chilled to a temperature of about 6.5 F – well below water’s normal freezing point – the water remained liquid.
