High Temperaure Plasma's behavior with other solids and liquids a Room Temp

  1. Oct 4, 2009 #1
    Recently, I came across some who suggested that a plasma between half the temperature of the sun (2889 K) and the temperature of the sun (5,778) would have the same burn patterns as lava.

    I felt skeptical about this for two reasons
    1. Lava's viscosity affects how it behaves. I did not think not sure that the viscosity of plasma would have the similar affect on plasma as the viscosity of lava has on lava
    2. The artificial plasma from a carbon arc lamp creates a kind of dust or soot that reasearch separate out to find graphine. Furthermore, plasma's range from almost but not quite 0 K to 10^8 K in magnitude.
    However, I really wasn't sure what plasma would do in general if it was between 2889 K and 5778 K.... so....

    What exactly would a plasma between 2889 K and 5778 do to a solid inorganic sustances like a rod of carbon or steel. What about to gelatinous compounds like Agar and Gelatin? What about to liquids like Midieval Glass, oil, and water?

    A lot depends on the density of the plasma, and the temperature and density together determine the energy that would be conducted into a solid.

    Plasma ions can knock out (ablate) the atoms of a solid. See - Plasma etching.

    At some density of plasma, sufficient energy flows (is conducted into) a solid such that the solid may turn to liquid.

    Hmm... I see... well this gives me something to look up at the library, so thanks ^_^.

    Anything else you might know would be helpful ^_^.
