Hot boiling water freezes faster when compared to temperate water. Scientists don't know the reason, but they have two suggestions that might explain this phenomena. The first proposal is that hot water circulate faster than normal water, so all particles will freeze at the same time. In temperate water, the upper layer freezes first, which insulate the lower layers, thus; decreasing the freezing rate. The second suggestion is that hot water will evaporate, and so lose energy at higher rate than temperate water, and so freezing faster. Scientists still don't know if these theories are true, or if there is another theory.
