This is an other side of the coin question about the freezing of hot water vs cold water, called the Mpemba effect.

The Mpemba effect is the subject of significant controversy. Here is an example of an experiment that failed to demonstrate such an effect:

I myself attempted a simplistic experiment in high school that failed to demonstrate the Mpemba effect.

It is reasonable to assume that if a sample of hot water and a sample of cold water are subjected to the same cooling process, the initially hot water will end up slightly warmer and therefore melt sooner.
