Boiling nitrogen
Boiling nitrogen is nitrogen gas produced when liquid nitrogen is heated at normal atmospheric pressure.

Boiling nitrogen vs Freezing water
What are they, and what does the difference actually look like?
Two things. One honest scale.
Meet the pair
What these two things are
Freezing water
Freezing water is liquid water at the temperature where it begins to turn into ice under normal pressure.
0 °CTemperatureBoiling nitrogen is 195.8 K cooler than Freezing water.

Celsius and Fahrenheit zero points are offsets. Compare temperature differences, not ratios in °C or °F. The kelvin axis starts at absolute zero.

Boiling nitrogen
Approximate normal boiling point at one atmosphere.
NIST Chemistry WebBook — Nitrogen phase data
The marked temperature is calibrated. Unmeasured illustration details are representative.
Freezing water
Fresh water at about one atmosphere. Dissolved substances and pressure change its freezing point.

- Comparing
- Temperature ↔ Temperature
- Relative size
- Temperature comparisons use an absolute difference in kelvins rather than a multiplicative ratio.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Boiling nitrogen is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
- Freezing water is labelled defined reference; treat the displayed value as a comparison anchor rather than false precision.
