Water acts familiarly at familiar temperatures. It freezes into ice at 32 degrees Fahrenheit, which corresponds to 0 degrees Celsius and 272 Kelvin. But “supercooled,” water can remain liquid even at temperatures as low as minus 40 degrees Fahrenheit.
Now, recent back-to-back breakthroughs are revealing the bizarre behavior liquid water adopts at the coldest temperatures ever achieved, Gizmodo reported. A new technique created by an international team of European researchers recently helped break the record for coldest liquid water by measuring a temperature of minus 44.59 degrees Fahrenheit (minus 42.55 degrees Celsius, 230.6 Kelvin for anyone wondering), according to the American Physical Society.
By tracking the diameters of microscopic water droplets in an evacuated chamber (meaning, vacuum-sealed with nothing inside, not even air) and illuminating them with lasers, the scientists were able to record measurements of unprecedented precision.
A paper describing the research was published in the scientific journal Physical Review Letters.
Meanwhile, a new technique has allowed a separate team led by physicists at Stockholm University to map the […]
