Is it true that hot water freezes faster than cold water?
Partly. Multiple peer-reviewed reviews and experiments report the Mpemba effect, in which initially hot water can freeze before initially cold water under specific conditions such as supercooling or ice-nucleating agents, while one small three-trial study found cold water freezing first. The evidence supports only a conditional version of the claim, not an unconditional one.
