# s-chem: more on the anomalous properties of water

<< Most of us know that water is essential for our existence on planet Earth. It is less well-known that water has many strange or anomalous properties and behaves very differently from all other liquids >>

<< Some examples are the melting point, the density, the heat capacity, and all-in-all there are more than 70 properties of water that differ from most liquids >>

<< These anomalous properties of water are a prerequisite for life as we know it >>

<< "The new remarkable property is that we find that water can exist as two different liquids at low temperatures where ice crystallization is slow" >> Anders Nilsson.

Water exists as two different liquids. June 26, 2017.
