boiling pointcheckmeasurement errormeasurement resultIt is shown that it is technically possible to use the boiling point of nitrogen when calibrating platinum resistance thermometers. An analysis of the origins and an estimate of the components of the error are given, and the limits of the error ...
When a person breathes air under pressure, the nitrogen in the air dissolves into the tissues of the body. When the pressure is removed from the body, the dissolved nitrogen gas comes out of solution, causing painful and potentially life-threatening conditions known as Type I and Type II deco...

The normal room temperature (20oC) is therefore way above the boiling point of nitrogen, so liquid nitrogen experiences film boiling under normal temperatures.

In the aforementioned methods, the presence of liquid nitrogen or other fluid for cooling applications is required, and furthermore, high-power pumping is necessary. The LNG can supply all the cooling processes, with significant savings, avoiding the employment of liquid nitrogen or other dangerous ...
Uncertainty estimation for extrapolation of the ITS-90 down to the boiling point of nitrogen from the triple point of argon We estimated uncertainty components associated with the extrapolation of temperature scales down to the boiling point of nitrogen (77.352 K) from a temperature scale of the st...
