Water has always been considered a well-known substance that accompanies us every day. However, the latest discovery shows that water can behave unexpectedly. Scientists from the Argonne National Laboratory have made a discovery that completely surprised them.
According to existing knowledge, water changes its state of matter at specific temperatures – ice melts above 0 degrees Celsius. However, scientists have discovered that ice can melt even below the freezing temperature. This discovery was completely unexpected and has been described in the scientific journal PNAS.
Water is still mysterious and holds many secrets. Michael Faraday noticed that the surface of ice is wet, even at negative temperatures, which raises the question of whether there are conditions in which water can exist in all three states of matter simultaneously. Scientists from the Argonne National Laboratory decided to investigate this topic and observed surface melting of ice at very low temperatures.
In one of the experiments, scientists demonstrate how, at a temperature of -123.15 degrees Celsius and constant pressure, the space between ice crystals fills with liquid water. Transmission electron microscopy was used to visualize the changes in the ice structure. This technique, which is used for electrolyte research, may contribute to the improvement of batteries. The research was conducted using liquid nitrogen, starting at a temperature of -143.15 degrees Celsius and gradually raising it.
This is just the beginning of research aimed at better understanding water. More data will help answer questions about processes that have so far been known only theoretically. The imaging method used by scientists from the Argonne National Laboratory will be a key tool in this puzzle.
