Supposedly, this has baffeled scientists for hundreds of years, even Aristotle tried to figure it out. And now, the Royal Society of Chemistry (RSC) is offering $1600 in order to figure it out. And, just in order to get some ideas going, Ill post one of my own. Obviously, we have to go down to the molecular (and possibly atomic level) in order to figure it out. We all know that once something becomes heated, the molecules become excited and start to move around more. Whereas, when something is cold, the molecules start to slow down. Perhaps, the excited molecules use up energy quicker when excited, thus, when exposed to cold, the molecules would slow down quicker. I know that there could be some problems with this, but it is the only thing I can think of. Hopefully, some of you out there could put up other and possibly better ideas?
Ordinary water has ions H2O =-OH + H Heated, molecular motion acceleration, the ion number more After cooling,-OH and H, the power of crystallization effects or acid-base reaction Accelerate the crystallization Test methods, added to the water reference electrodes, metal electrodes to measure current, voltage change I guess
