can hot water freeze faster than cold water?

Yes, in some specific circumstances, hotter water freezes faster than colder water. All explanations are still hypotheses and there is no fully proven explanation yet for why. It's known as the Mpemba effect.

This is true, in some specific, rigorously controlled circumstances, hotter water freezes faster than colder water. This is because the escape of heat of evaporation can cause the hotter water to lose its heat and crystalize immediately. It goes from being a liquid to solid rapidly. Take a cup of boiling water outside in Antarctica, throw it in the air, and it will hit the ground as ice. Take a second cup of 40 degree F water, do the same, and it will still be water when it hits the ground.

No. The first thing that has to happen to freeze a substanceis to take it to the freezing point. Then the heat of fusion has to be removed as the mlecules get closer together and line up to form crystals. If you have to reduce the temp further, it does not freeze faster.

yes, go boil water when its below freezing outside the take the water through it in the air and watch. Then do it with cold water you can see the results yourself.
Science behind it has to do with the molecules being separated when heated; being separated allows them to be cooled faster hence water rapidly freezes when hot.

yes hot water freezes faster, its a proven fact it makes a chemical reaction between hot and cold. if you want to test this out use ice trays and see for your self. we did it when i was in high school.

Yes, it's called the Mpemba effect.
Although this is not a common occurance, it does happen.
