True. Maybe posting that calculation isn't really worth doing as different
amounts/types of antifreeze will alter the boiling point in any particular
cooling system. I may not be able to find that info anyway.
If I find it, I'll post the calculation for the boiling point for pure water
as pressure increases above standard (14.7). The phase change is actually a
different issue. Steam (at standard pressure) is the same 212 degrees as
boiling water but steam has more energy than boiling water. This is called
latent heat. Again way too long since I did these calculations. 1 btu is
the amount of heat needed to raise one cc of water one degree centigrade at
STP. So if that 1cc of water were at 0 degrees C, 100 btu's will raise that
1 cc of water to boiling. From there it's something like a further 900
btu's to convert that boiling water to steam.
With that I'll shut up so as not to send anyone on the list past their
boiling point.

It's not that simple - there is a phase change curve (solid to liquid to
gas) that is
different for different materials. There is one for pure water, but if you
change the
composition of the fluid, by adding anti-freeze, for example - you change
its phase change
characteristics.
