然后，如果外部温度在加热和未加热样品的冰点之间，则“热”水不仅会首先冻结，而且是唯一冻结的水，而不管其他情况。这些条件可以在无意中通过水壶（类似或不类似）和管道中的热水和冷水实现多次。我们中的许多人都观察到类似的现象，即在寒冷的天气下打开一瓶碳酸饮料。液体不会冻结，也不会在摇动时冻结（可能不会过冷），但当盖子被移除时，液体可能会突然冻结固体或变成冰晶糊状。液体的温度在具有和不具有所述温度的液体的冰点之间。
Then, if the external temperature is between the freezing-points of the heated and unheated samples, the" hot" water will not only freeze first, but will be the only one to freeze, regardless of all other circum-stances. These conditions could have been fulfilled un-wittingly many times by kettles of water (alike or un-like) and by hot and cold water in pipes. Many of us have observed a similar phenomenon in opening a bottle of carbonated beverage which had been outdoors in freezing weather. The liquid is not frozen and doesn't freeze on shaking (probably not supercooled), yet when the cap is removed, the liquid may suddenly freeze solid or become mushy with ice crystals. The temperature of the liquid was between the freezing-points of the liquid with and without the
