What is the boiling point of water at standard atmospheric pressure, in degrees Celsius?

Answer

100
answer
the number, as a whole number with no separators
source
Answer from a reputable public source you actually read (the Nobel Prize site, NIST, Britannica, or a peer-reviewed journal's site) and name it.
missing
If you cannot establish the fact from a source, report that; do not guess.
