Why does Boiling water freeze faster than cold water
Here is my simple PHYSICAL (Physics) explanation to whats happening.
Imagine Water molecules as cars , the faster the car drives when a car crashes into another car the greater the force exerted on the frame of the car therefore the quicker (FASTER) the cars slow down on impact.
Whereas slower cars that hit each other the energy is absorbed like a shock absorber and therefore provides a spring back effect.
Upon impact high speed cars or molecules suffer from a different type of stress on the bonds in a similar way a car frame would.
