Why does boiling water freeze quicker?

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

Does hot water freeze faster than cold water Mythbusters?

It’s an age-old question with a simple answer: no. When the temperature of the water in each container reaches just about 0°C it will undergo the same changes as it moves from a liquid to a solid, and it will take the same amount of time to begin forming tiny ice crystals. …

Why does boiling water freeze in mid air?

This happens because the hot water is so close to being steam, that the act of throwing it into the air causes it to break up into tiny droplets. … And finally, the cooled droplets are so small, that they can be easily frozen by the winter air.

Do ice cubes freeze faster with hot water?

Why hot water freezes faster.

The molecules initially tighten up and bind together to create a solid form. … Cool water would take time to reach this point. Ergo, hot water freezes in less time than cold water does. So next time you’re in a pinch and need ice cubes ASAP, just boil up some water to freeze.

What liquid freezes the fastest?

Water did freeze the fastest with an average of 56.6 minutes.

What boils faster hot water or cold water?

Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does.

How cold does it have to be to freeze boiling water instantly?

The smaller streaks are from condensate coming off falling water droplets — not water that has frozen midair. The air is not quite cold enough to freeze water immediately, which happens at about minus-42 degrees, Terry said.
