Why hot water freezes faster than cold?

A student asked his teacher a question: "Why, if you put in the freezer two capacity — boiling water and water at room temperature freezes first hot water?" This question stumped Professor Denis Osborne. Not finding the answer, Osborne made a scientific article, calling this phenomenon the effect Mamba.

To explain this effect is tried in the time of Aristotle, but until now nobody was able to prove scientifically why hot water freezes faster than cold. Because Brian Emsley, head of media relations the Royal society of chemistry, announced a prize of 1,000 pounds to anyone who will be able to reveal this phenomenon.


Previously, many tried to explain this phenomenon is a normal physical effect, but none of the explanations are accepted as final. Put forward the theory that hot water freezes from evaporation, convection or hypothermia.
