In literature:

The inert gas, nitrogen, had been discovered a year or two before.
"Scientific American Supplement, No. 362, December 9, 1882" by Various
The only inert and useless gas in an arrangement like this is the nitrogen of the air, which being in large quantities does act as a serious diluent.

"Artificial Light" by M. Luckiesh
The nitrogen is an inert, odorless gas, and its use in the air seems to be to dilute it, so that man and animals can breathe it.
"Nature's Miracles, Volume 1" by Elisha Gray
The volume of flame, however, is increased by inert gas, and there is a proportionate diminution of the heating effect.

In science:

Benzene (Tm = 279 K, Tb = 353 K) was bought from Sigma Aldrich (99.9% puriss. p.a.), unpacked under inert gas and sealed into a Duran cuvette.

Knudsen experimentally observed that, no matter how an inert gas was injected into a pipeline, the direction in which a molecule rebounds from the pipeline’s solid wall is asymptotically independent of its initial tra jectory.
Knudsen's law and random billiards in irrational triangles
In contrast to this, SIMPLE modules contain a considerable volume of inert liquid (glycerol) and gas (compressed N2 ) above the active gel, and cannot be recompressed due to the fragility of their glass containers.
Comments on "Final Analysis and Results of the Phase II SIMPLE Dark Matter Search"
This produces a rapid aging of the detector material, leading to gel fractures and a diffusion of the superheated liquid into inert volumes and fracture voids, increasing the pressure inside the module and ultimately leading to gas leaks occasionally able to produce characteristic acoustic signals.

Indeed, there is a band of speeds (s∗ , s∗ ) about the characteristic speed f ′ (u+ ) for which neither detonation nor deflagration connections exist, in sharp contrast to the inert-gas, shock wave case.

If the state of an inert gas changes very slowly, then its physical behaviour can be modeled well by results derived from the Gibbs model.
Objective Methods for Assessing Models for Wildfire Spread
This model works well because the fundamental units are atoms of an inert gas, which have simple structure and which interact rarely.
