Verified step by step guidance1
Understand that the normal boiling point of a substance is the temperature at which its vapor pressure equals 1 atm (standard atmospheric pressure).
Recognize that nitrogen (N\_2) is a diatomic molecule with well-documented physical properties, including its boiling point at 1 atm pressure.
Recall or look up the standard boiling point of nitrogen from reliable data sources such as tables of physical constants or chemistry reference materials.
Note that nitrogen's boiling point is much lower than water's (373 K) because it is a small, nonpolar molecule with weak intermolecular forces (London dispersion forces).
Conclude that the normal boiling point of nitrogen at 1 atm is approximately 77 K (about -196 \degree C), which matches the known physical property of nitrogen.
