As long as it is under normal pressure, the temperature range of ice can be -273.6438+05 degrees to 0 degrees, and H2O appears as a solid in this temperature range.

The temperature of the ice-water mixture is 0, which should be because if the temperature is to be lowered again, all the water must be frozen first, and there will be no water below 0. When all the water turns into ice, the temperature of the ice can continue to drop until it reaches the ambient temperature.

Ice is the solid form of water in nature. Under normal pressure, when the temperature is higher than zero degrees Celsius, the ice will begin to melt and become liquid water. A Japanese research team found that when the ice began to melt, a water molecule in the crystal began to break away from the crystal, and the related mechanism was helpful to understand the structural change mechanism of protein containing water.

If the ice is irradiated with strong light such as electric light, the inside of the ice will melt and appear a shape similar to snow crystal, which is called "ice flower". In order to investigate the phenomenon of ice melting from the inside, researchers from Japan Institute of Molecular Science and Okayama University calculated by computer what happens to ice formed by about 1000 water molecules when heated.
