Does ice made with hot water melt faster than ice made with cold water?

Question

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

Answer 1

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.

Answer 2

Ice made with hot water tends to contain less dissolved air. The latter tends to lower the freezing point, so ice made from cold water will melt at a higher temperature.

Answer 3

first of all ice made from hot water tends to freeze much earlier than water from cold water this is explained through Mpemba effect see this wikipeda article for more information https://en.wikipedia.org/wiki/Mpemba_effect Although i want to clearly state you that this effect is still not accepted by mainstream scientists today and is still debated As far as Melting of ice is concerned once it freezes at 0 degree celcius it does not really matter it is made of hot water or cold water both types of ice will melt at 0 degree celcius.The melting point of ice at 1 atmosphere of pressure is very close [3] to 0 °C (32 °F, 273.15 K); this is also known as the ice point.
