At what temperature will water begin to freeze?

At standard atmospheric pressure, at zero degrees Celsius, water will begin to freeze.

At atmospheric pressure, the melting point of ice is 0℃. When water freezes at 0℃, its volume will increase by about 1/9 (the minimum water volume is 4℃). It has been observed that when water freezes under closed conditions, the pressure generated by the volume increase can reach 2500 atmospheres.

Generally, when the temperature is 0℃, water may not freeze, because the temperature of water does not reach 0℃, but is in a low temperature state.

Freezing, also called freezing, is a weather phenomenon. Open water freezes into ice. Meteorologically, water, including evaporating dishes, freezes.

In most parts of China, there is icing after beginning of winter. Winter means the end, which means that the crops should be harvested after harvest. In ancient China, people used to regard beginning of winter as the beginning of winter.

Freezing point refers to the temperature at which crystals change from liquid to solid. For example, the freezing point of water is 0℃ (Celsius), and the freezing point of liquid nitrogen is-196℃ (Celsius).
