Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e.

Water behaves in remarkable ways when heated and pressurized beyond its critical point. Under these extreme conditions, known as supercritical water, it no longer acts like an ordinary liquid. Instead ...

For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up electrons to form oxygen. In the crucial moment before producing oxygen, ...

Scientists have discovered the potential existence of a bizarre new molecule related to water. Dubbed “aquodiium,” this ion could form under extreme conditions and may explain some of the weirdness of ...
