In a new research published by Austin Angell, who is the chemist from the Arizona State University, intriguing properties of water have been found. He has discovered a new phenomenon wherein on sufficient super cooling or under specific conditions water can suddenly change from one liquid to another one, this new liquid is still water but is of a lower density and with a different arrangement of hydrogen bonded molecules, such that the bonding is stronger and hence the liquid or the water is more viscous. In 1994, by making use of pure pressure as a force for driving transition of liquid, pure water was transited from one glassy state to another.
This new phenomenon had been previously seen in computer simulations of water models. The problem with getting to see this phenomenal in real water is that it crystallizes suddenly into ice. The new liquid which is more viscous, is also glossy and by reversing the direction of change in temperature the original solution before crystallization of ice occurs can be obtained. These findings offer a general explanation regarding the thermodynamic anomalies of water in its liquid state. It also validates the second critical point theory which was put forward by Gene Stanley’s group which tried to explain the anomalies of water. Very few other substances apart from water are thought to exhibit these properties. In fact other substances are simply thought of as to exhibit these unique behaviours, as none of it has been proven till date.
