How many degrees below zero will freeze?

Water condenses from liquid to solid below 0 degrees Celsius, which is called freezing.

It should be pointed out that:

Generally, it can't freeze at 0 degrees Celsius. Zero degree is freezing point. No impurities will freeze at 0 degrees, and some impurities will freeze below 0 degrees, about 3 degrees below zero.

Below MINUS 4 degrees, the density and volume of water will increase. If you put water in a bottle in winter, it is likely that the bottle will break due to the increase of its volume.

Extended data:

At standard air pressure, it will freeze at 0 degrees. But 0 degrees will also be liquid and solid. So there will be an ice-water mixture at 0 degrees.

Salt can prevent water from freezing.

The freezing point of seawater is lower than that of fresh water.
