Webb15 juni 2024 · There are a number of factors that can affect how quickly water freezes. One is the purity of the water – impurities can act as “nucleation sites” that encourage ice crystals to form. The presence of salt, for example, can lower the freezing point of water, making it freeze more quickly.
