Boiling water freezes faster
WebAll things being equal, cold water freezes faster. It takes time for the energy contained in a hot object to be transferred to a cold object. However, the rate of heat transfer is proportional to the temperature difference between the two objects, so hot water will lose heat faster than cold water. In other words, if you have water at 90 ... WebQuestion Date: 2005-02-09. Answer 1: Intuitively, one would say that cold water freezes faster, because it is already cold and therefore needs less time to cool down all the way to its freezing point. Hot water would need to be cooled more to get all the way to the freezing point, and it would therefore take longer to freeze it.
