Since, by your own admission, the boiling and freezing point
temperatures of water are pressure dependent, I invite you to state
what pressure would be required to be exerted on a volume of liquid
water in order to cause it to boil at 0°C.
The answer of course is: not much.
Hmmm...
Same as the answer to: "What does Floyd L. Davidson know about
anything?".
He appears to be confusing sublimation and evaporation with boiling.
*Look* at the statement:
Water can "boil" at 0C too.
It is *correct*, as you've all been very hasty to demonstrate.
It is not so precise as to say "at 0.010C", but certainly that
value is well within the normal meaning of "0C" (what, -.5 to
+.5 C!).

Whether it's "correct" or not is moot. What you were challenged to do
was to provide the _pressure_ required to make water boil at 0°C. You
The pressure is commonly known, was not the point, and your
question was out of place and trivially ignored.
Which is to say, who cares if you asked a dumb question?
And while sublimation might happen at that temperature too, as
might just simple evaporation, the fact that it doesn't break
into a full nucleate boiling state does *not* make what was
stated wrong either.

"Existing as a vapor" doesn't constitute boiling, dumbass.
