The inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non-ideal gas (all gases in reality) that is expanding at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase.
A gas must be below its inversion temperature to be liquefied by the Linde cycle. For this reason, simple Linde cycle liquefiers, starting from ambient temperature, cannot be used to liquefy helium, hydrogen, or neon. They must first be cooled to their inversion temperatures, which are -233 C (helium), -71 C (hydrogen), and -42 C (neon). [11]
A temperature inversion in Bratislava, Slovakia, viewing the top of Nový Most (2005). Inversion-created smog in Nowa Ruda, Poland, 2017 Temperature inversion phenomenon in the early morning near Tawau, Sabah, Malaysia where smoke that was emitted from an oil palm mill stayed close to the ground. The wind carried the smoke in the direction of ...
Surface temperature inversion is typical of polar environments and leads to the katabatic wind phenomenon. ... Carbon dioxide (CO 2) is of particular interest in ...
The Redlich–Kwong equation is very similar to the Van der Waals equation, with only a slight modification being made to the attractive term, giving that term a temperature dependence. At high pressures, the volume of all gases approaches some finite volume, largely independent of temperature, that is related to the size of the gas molecules.

A population inversion (N 2 > N 1) has thus been achieved between level 1 and 2, and optical amplification at the frequency ν 21 can be obtained. Because at least half the population of atoms must be excited from the ground state to obtain a population inversion, the laser medium must be very strongly pumped.
Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...
