STP - Standard Temperature and Pressure. Jack with pressure and the
temperature specs change.

Take the pressure off water e.g. vacuum and you can boil it.
In the reverse pressure up the water and it can't boil. e.g. no steam.
Release the pressure and zap, almost instant 100% steam. Sometimes
dangerously.

It is impossible to heat water above it's boiling point. At that point it
