I don't know which freezes first, but I do know
that if your water pipes freeze, the hot water pipes break more often, and take
longer to thaw.
I've been told by plumbers it's because the water
that has been heated has fewer air bubbles,( steamed away) so freezes harder
than the cold water pipes.
And if you want pretty, crystal clear ice cubes for
your party drinks, boil the water before you put it in the ice cube
trays. (Just trying to fancy things up for the party you
are having for your endurance riding friends.) {;>)

Perhaps they were incorrect, but they have been long
remembered. Will we be remembered as long?

"...Also take into account that hot water has
more minerals dissolved in it ..."
Actually, things are a bit more complicated than
that. Some things like sucrose are more soluble in hot water, some
things like table salt are only slightly more soluble in hot water, some
things like dish detergent are more soluble in cold water. It all
depends on Entropy, heat of solution and the rest of the boring laws of
thermodynamics.
As a scientist, it is very hard for me to believe
that anyone could come up with plausible explanation, in line with the 3 laws
of thermodynamics, that would allow for the effect being discussed
here. Even the proponents admit that the effect does not always
happen. I did note that some of the authorities quoted are the same
one's quoted in the dark ages in discussions of medicine and
science.
