If you are asking for the definition of a boiling point then we can help.


The boiling point of a liquid is the temperature at which the vapour pressure of the liquid is equal to the ambient pressure, and bubbles of vapour (= gas) form directly in the liquid.

The #"normal boiling point"# is specified when the ambient pressure is equal to #"1 atmosphere"#, and thus the vapour pressure of the liquid equals #"1 atmosphere"# at the normal boiling point.
