It turns out that what we drink every day is the weirdest liquid in the universe

We have known a lot about water and its characteristics. But not everyone realizes that these properties are extremely different, but they travel across the universe, and we find it difficult to find the second.

For our species, water is a familiar and strange material. Familiar with water that covers 71% of the Earth's surface, found in most living organisms, accounting for up to 70% of human body mass .

But water is also very strange because of its special properties, so far, scientists have not been able to explain it all.

For our species, water is a familiar and strange material.

The first thing to mention is the density of water. When the temperature drops, most liquids will shrink. But water only follows this rule as long as the temperature stays above 4 degrees Celsius. If it is lower, the lower the temperature the water will expand. It also means that water has the largest density of 4 degrees Celsius.

The next special point is stone. When we put cold ice in the water, we see that ice always floats on the surface. This phenomenon is so common in life that you often ignore it.

But it should be noted that a solid substance is usually denser than itself in liquid form. Thus, should the cold stone sink in the water, right?

Stone floating on the water.

Not only that, water has a larger boiling point and surface tension than many other liquids. Water also dissolves very well. Therefore, water has a great biological significance and is dubbed the "solvent of the universe".

When looking for ways to explain the different characteristics of water, researchers from Bristol University (UK) and Tokyo University (Japan) used a supercomputer to rebuild the water molecule model. They found that at room temperature, water molecules have a tetrahedral structure.

It is this pyramid's arrangement of atoms that allows water to have the capabilities that most other liquids do not have.

Tetrahedral structure of water molecules.

In further experiments, experts simulated water molecules with different arrangements. As a result, when the pyramid structure is no longer available, the water loses its special properties and becomes a normal liquid.

John Russo, the head of the research project, said: "Through this experiment, we know that the tetrahedral structure is the reason why water has different properties from other natural fluids. " .

"We hope the results of this project will contribute to explaining the mysteries of water" - he added.

The study was published by the National Academy of Sciences (United States).

In addition, the country has many interesting things that we do not pay attention to. Let's read the article to discover these interesting things.
