Boiling Water!

Which boils faster, water that is initially cold, or water that is initially hot? How much does watching a pot really effect boiling times? If noone has a definitive answer, I’ll be forced to perform and experiment to find out once and for all.

Before you go to all that trouble, I suggest you search the SD and SDMB for previous times this question has been asked.

Quicker yet is this simple answer:
Hot water boils faster, watching it doesn’t do squat.
Check the archives for an expanded explanation.

And while you’re at it, you can also learn which freeze’s faster. Hot water or cold.
