If hot water freezes faster than room temperature water, does cold water boil faster than room temperature water?

You're right that under some conditions, hot water
can freeze faster than cold water does. This phenomenon is known as the
Mpemba effect, and there are a lot of different guesses as to why it
happens. For more information on this, check out the answer: Freezing Hot Water and the Mpemba Effect
is a special effect that occurs only for freezing, and it is not what
most people would expect to happen. Boiling works just like you'd
probably expect - hot water will boil more quickly than cold water. If
you want, you can try this on your stove at home to be sure.
