|Ice is colder than 32 degrees. How much colder depends on where it came from, ie the freezer temperature. When one dumps it in water, the water exchanges energy with the ice, so the ice changes state, and the water gets colder. The water can get no colder than 32, or it changes state to solid. Thus, a mixed phase solution exists. A well mixed liquid portion will have a temperature close to the freezing point. The solid phase developes a temperate gradient, with the outside being at 32, the core colder, and the cube slowly melting, and moving the whole system toward equilibrium. Yet, the core of the ice cube will be colder than 32 degrees, until it is close to being completely melted.|

This thread made me remember some of my thermodynamics courses at the university
I think what Swampfox is trying to explain is the fact that solid water (ice) can coexist with liquid water depending on a precise pressure-temperature condition.
It's curious.... Now that I'm taking a second look at the diagram, I think I may design a pressurised chamber
For a second I'm pretty sure I might hear angels playing sweet music... before I get a bad short circuit and my audio gear completely ruined :mrgreen:

BTW, a friend of mine insisted that crogenically freezing a CD would improve the sound and my logic center cut in and said "QUE?!?" So he demonstrated the difference with the same CD, one froze, one not, and, to my surprise, I could easily tell the difference. Unfortunately, I was "wrong". Each frozen disc sounded obviously worse with more "hash" in the signal. He said I was hearing the "space" between the notes, but what I was more likely hearing was.........error correction.

Are you using plain old tap water or expensive bottled water? We all know this could make a major difference as the expensive water would enhance the boiling process tremendously. I'm fairly certain that the country of origin of the bottled water would also be a determinate variable.

I know this is a joke, and your being sarcastic. . . Yet, the origin of water could lead to differences in the mineral content which could change the boiling point.
