hot water freezes faster than cold water

[The artist formally known]

it's true

[Walter]

Ya its true. I have a theory about it.

When water freezes it expands. Room temperature water is more condensed. Heated water is less condensed then room temperature water. Room temp water has to expand more then the heated water does, so it takes a bit longer.

[Selkie]

And cold water boils faster than hot water
