Water has two liquid phases with different densities and structures at low temperatures.
In fact it behaves very differently to other liquids in more than 70 properties such as melting point, density, heat capacity, these anomalies are a requirement for life as we know it.
A team from the University of Stockholm has discovered something surprising. It turns out that water is not a liquid, but two. That is, it has two liquid phases with different densities and structures.
It was discovered that water can exist as two different liquids at low temperatures, where the crystallization of ice is slow. Water, therefore, can exist as two different liquids.
The new results give strong support that water at room temperature can not decide which of the two forms should be, at high or low density, which leads to local fluctuations between them, explains physiochemical professor Lars G.M. Pettersson Water is not a complicated liquid, but two simple liquids with a complicated relationship.
In addition to the global understanding of water at different temperatures and pressures, the study will also clarify how water is affected by salts and bio-molecules important for life.
All this knowledge is important to face one of the greatest challenges of humanity in the future, which will be to purify and desalinate water in a world punished by climate change, to be able to supply millions of people in the world who do not have access to water. water and for which cause more than 5 million people die every year in the whole planet.
If we also do not create awareness for its use and if we do not stop polluting it, the water will be exhausted in the universe and this combined with global warming, climate change and the waste of the liquid the end of life on the planet, life depends on the water for all the activities of organized life or not and if we do not take care of it, we are doing away with life.
