Scientists successfully discovered water that remains liquid at 68 degrees below zero.

According to source Tech Explorer, a group of physicists from the City University of New York became the first to receive water that remains liquid even when cooled to a temperature minus 68°C

During this study, the group was able to prove that water itself consisted of at least two different types of fluids, which had different physical properties, the journal added.

In theory, water can remain liquid at temperatures below 70°C, but achieving this on the ground has been very difficult.

But the Group of American Physicists succeeded in solving this problem, not by cooling water, but by heating high-density amorphous ice in a particular way using an infrared laser capable of producing very strong, but very short, thermal radiation pulses.

It is noted that these flashes of light were so short that the intensity of the water sample did not change when the ice melted. This allowed scientists for the first time to see how high-density water forms and follows its transformation - a transition phase - into low-intensity water by lighting melted ice using an X-ray laser.

The follow-up confirmed that both types of fluids had different properties, and also showed that dense water was about 20% heavier than its light version. The experience has shown that, under certain circumstances, these two forms of chilled water do not mix with each other.
