What weather will the temperature freeze?

At high temperature, the kinetic energy of water molecules is too great to generate hydrogen bonds firmly, and the molecules are arranged in disorder as small as possible. When the temperature decreases (below 4℃), less and less kinetic energy of molecules is not enough to break hydrogen bonds, and hydrogen bonds have a certain bond length, so more and more hydrogen bonds are fixed after 4℃. When the temperature is 0 degrees, all molecules are fixed in a certain area, and hydrogen bonds keep a certain distance between molecules, which is ice.

The frozen volume of water increases by110, so the volume ratio of water and ice with the same mass is 10: 1 1.

It is abnormal that water expands with heat and contracts with cold. When the temperature is lower than 4℃, water contracts and expands, resulting in a decrease in density, and when it is higher than 4℃, it will resume thermal expansion and cold contraction. This is one of the most important and peculiar characteristics of water. This is a very important point to ensure the existence of organisms. When water freezes, the density of ice is small and it floats on the water surface, which can ensure the survival of underwater creatures. When the weather is warm, the ice is on it and thaws first. However, if the density of ice is greater than that of water, the ice will continue to sink underwater and will not thaw in warm weather. The water above will continue to freeze for the next year, until all the water turns into ice, and all aquatic life will cease to exist.
