I am calibrating thermocouples. Is that not allowed? More calibrations and more specific information about temperatures, duration, the mass of metal and the mass of cooling water would enhance this discussion.

To paraphrase the monster in "Frankenstein" and "Bride of Frankenstein":

Calibrations, good. Heat, _go-o-o-od_. Blather, bad. Unfounded speculation, bad.

I measured the approximate enthalpy of steam a couple of months ago, with an electric frying pan. I did not observe the miraculous event that skeptics believe is so common, wherein the water disappeared at 7, or 20 or 1000 times the textbook rate. Due to inefficiencies and the frying pan heating the room air, I found it took considerably more energy to boil away the water than the textbooks indicate. No surprise.
