Could a cold plasma be densified until its particles are so densely pasted together that it behaves like a solid without reaching extreme temperatures? If so how? Edit: okay there seems to be a confusion. I’m not trying to cool the plasma but simple push the particles so close together that they are equal in density to solids. There’s no reason it shouldn’t be able to do this and be still considered a plasma like substance because the moment the pressure holding it together (electromagnetic field) is relived it goes back to classical plasma. I just want to know if increasing the density of cold plasma would make it hotter?
