why hot water freezes faster than cold water

[Mugwump]

Have scientists worked out why hot water freezes faster than cold water?

It is a phenomenon that has baffled the world?s brightest minds since the time of Aristotle.

Now a team of physicists believe they may have solved the centuries old mystery of why hot water freezes faster than cold water.

Known as the Mpemba effect, water behaves unlike most other liquids by freezing into a solid more rapidly from a heated state than from room temperature.

Scientists have suggested dozens of theories for why this may occur, but none have been able to satisfactorily explain this strange physical property.

A team of physicists at the Nanyang Technological University in Singapore have now published what they believe may be the solution.
