PeaceCrew the methods you have been exposed to and had explained to you as able to be used to calculate temperatures of objects immersed in cold Nitrogen baths, are wrong.

And have ZERO to do with any temperature

of any light warmed object,

immersed in any cold, light blocking, oxygen enriched,

greenhouse gas-refrigerants laced,

Nitrogen bath.

Stefan Boltzmann is NEVER used, e v e r.

NOT

ONCE

in actually calculating the temperature of any object

immersed in any cold bath.

NEVER.

This cannot be stressed enough to you.

Stefan-Boltzmann is NOT one of the GAS laws.

Temperatures of things immersed in cold gas baths, calculated using Stefan-Boltzmann, will ALWAYS ALWAYS ALWAYS derive an erroneous value.

The method Stefan Boltzmann uses, does NOT work, on gases.

Gases are the compressible fluids

phase of matter.

It's why they have their OWN LAWS and Stefan-Boltzmann

isn't

one of them. EVER.
