At What Temperature Does Moving Water Freeze?
Water typically freezes at 32 degrees Fahrenheit (0 degrees Celsius) when it is not moving. However, the freezing point of moving water can be significantly lower due to the effects of supercooling. Supercooling occurs when water is cooled below its normal freezing point but remains in a liquid state due to the absence of nucleation sites that trigger crystallization.
When water is moving, it is constantly creating new surfaces, which provides more opportunities for nucleation sites to form. This means that moving water can remain liquid at temperatures well below its normal freezing point.
The exact temperature at which moving water freezes will depend on several factors, including the speed of the water, the presence of impurities, and the size of the water droplets. In general, smaller droplets and higher speeds will lead to a lower freezing point.
