Researchers at the University of Birmingham and Sapienza Università in Rome have revealed a unique water property, which was first proposed three decades ago. This can change and change into two different liquids in what is called a phase transition. However, it happened at a very cold temperature.
But, isn’t water converting solids into ice at low temperatures?
Yes, so, and that is what remains the biggest challenge in confirming theories that have confuted scientists for almost 30 years. They stated that because chemical work was hidden in water, the reason why that happened was still mostly unknown about the liquid-liquid transition.
The findings of this study have been published in the journal Nature Physics, which states that the prominent feature of liquid water is the anomaly behavior of the thermodynamic response function in cooling, the most famous is the maximum density at the surrounding pressure. Francesco Sciortino, now a professor at Sapienza Università in Rome and colleagues of the author of this study was part of the original team, who in 1992 proposed the idea of the liquid-liquid phase transition in water. “In this work, we propose, for the first time, the view of the liquid-liquid phase transition based on network attachment ideas. I am sure this work will inspire new theoretical modeling based on the concept of topology,” he said in a statement.
While the form of fluids with high density has molecules that are arranged in such a way that they resemble pretzel, they are entangled, while molecules in the form of low density have mostly rings and therefore nicknamed not dependent.
The researchers, according to the University of Birmingham, used the colloidal water model in their simulation, and then two molecular water models were widely used. Colloids are particles that can be a thousand times greater than a single water molecule. Based on its relatively larger size, and therefore the movement is slower.
“This colloidal water model provides a magnifying glass into molecular water, and allows us to uncover the secret of water about the story of two liquids,” said Dr. Dwaipayan Chakrabarti, author of the paper, in a statement. This study aims to look into water and find movements and chemistry occurs at the molecular level, which can be analyzed and explored further.
“Water, one by one, reveals the secret! Dreaming how beautiful it is if we can look into the liquid and observe the dance of water molecules, the way they blink, and the way they exchange partners, restructured tissue hydrogen bonds,” Scortino added.
