The discussion revolves around the effects of ionization on the velocity of ionized nitrogen atoms and the overall temperature of the gas. Participants explore the implications of adding energy to nitrogen gas, specifically focusing on the ionization process and its consequences.
Participants do not reach a consensus on the specifics of how ionization affects velocity and temperature, and multiple perspectives on the effects of energy input remain present.
The discussion includes assumptions about the nature of nitrogen gas and the ionization process, as well as the dependence on how energy is applied to the system. Specific mathematical details and formulas for calculating changes in velocity are not provided.
Atomar nitrogen gas, where you magically prevent the formation of molecules? You'll both heat it and ionize some fraction of the molecules. The relative magnitude of those effects will depend on the way you put that energy into the system.Intle said:If I add 1402kJ of energy to 1 mol of Nitrogen I will ionize it, as I understand it.
I see. I asked in an earlier question what an easy gas would be to ionize and to get, and I was recommended air which is primarily composed of nitrogen and oxygen but never mind, on further research I see that it actually forms bonds with itself, so you are correct. Sorry about that. However, in fact I am more interested in calculating this change in velocity for ions directly after ionization. Is there a formula I can use?mfb said:Atomar nitrogen gas, where you magically prevent the formation of molecules? You'll both heat it and ionize some fraction of the molecules.

An ionization process typically gives kinetic energy to both the electron and the remaining atom, but the electron gets much more energy. It can transfer this energy to other particles afterwards, heating the gas.
