Among all the substance found in the surface of the earth, water is the most precious one. It is the prime necessity for sustaining life on this planet.
It is everywhere. Earth is filled with about 71 percent water and oceans contains more than 96 percent of the available water present in the earth. If you think only water is present in the nature, you can’t be more wrong, human body is also made up of 60 percent water.
Unlike other matter present water has some unique abilities. It is also doesn’t behave like other fluids discovered till now. Recently researches have discovered a new property of water, which helps it to exist in dual liquids at low temperature. One have a higher density form and other one exists in lower density form.
Head professor of chemical Physics of Stockholm University states that, the new property discovered by them in which water can remains in two distinct fluids at low temperature is due the property of Ice crystallization is moderate in nature.
The researches made the discovery in Argonne National Laboratory in Chicago. The discovery is only possible due to the availability of high precision X-ray analysis to water molecules at controlled temperature. Also further study on this matter is going on in DESY in Hamburg.
Fivos a student having a vast background of ultrafast optical spectroscopy is doing post doctorate on behaviour of water molecules in Stockholm university states that, it is very interesting to discover this property of water. This discovery will definitely help in some on going research of behaviour of other fluids, earlier which is not possible due to non-availability of precision microscopes for research purposes.
Earlier we are only able to follow the rate of transformation of water at low temperatures only. But with this we can also see the transformation behind the two different phases of the diffusion of molecules, which is very rare in case of other liquids.
Extensive research on water is going on because it has so many anomalous properties which other liquids at the same temperature doesn’t have. Scientists re-trying to find the reasons behind the anomalous properties of water like melting point, boiling point, latent heat etc. This discovery of two states may give us some insights about those unexplained trends in water.
