# Plasma, what is its density?

We have a fluid (gas or liquid) with a density "X". And we apply a voltage to convert the fluid plasma.

Will the plasma have a density > "X" or density < "X"? Could you give me some examples with numerical values?

Thanks

Hugo Peraza Rodriguez· University Carlos III de MadridWell, for getting to the plasma state you have to increase the temperature, first to reach a gas and the to ionize the gas, so the density is going to be less than X. What it's density is will depend on the degree to which it is ionized (check Saha's equation). Usually it is considered fully ionized, and then you have two fluids (electrons and ions), each with it's own density.

Typically, for plasmas under a given potential, its density can be described by the Boltzmann relation: http://en.wikipedia.org/wiki/Boltzmann_relation

Maybe if i get a significant volume of plasma at high pressure, i can get a great light. Something like a very strong fluorescence.

Anyway, Daniel, you say it would be a simple calculation of pressure, right? In plasma data I am lost.

Suppose 30 grams of Nitrogen, for example, (23.98 liters approx in normal conditions), and apply a ionization energy 1402.3 kJ / mol (the 1 st ionization energy). How I can I calculate the volume of N2 plasma state? And changes in the density? What formulas and / or theories could be applied to obtain the result?

Thank you very much, this support is vital for me!

Muhammad Zubair Khan· Federal Urdu University of Arts, Science and Technologywithin Plasma, it is already defined those mentioned parameters ranges. if range is less than the defined ranges, then you will not say it is plasma , it will be called normal ionized gas but will never be considered Plasma.

Generally, plasma density is actually the electron density or some time called electron plasma density.

you can study all about Density or Plasma Density online on different websites,

after seeing you will be well aware about answer of your question.

Mangilal Choudhary· Institute for Plasma ResearchDeletedDonald Berk· White Quill LLCJavier Luis López· Pulsotron SLParticles/m3, that is given using Avogadro number

Also it could be used ionized particles/m3 that is the usual number used in partially ionized plasmas that is the particles/m3 multiplied by a factor between 0 and 1 that is the percentage of ionization as said Mangilal
