  2. Plasma (physics) - Wikipedia

    en.wikipedia.org/wiki/Plasma_(physics)

    Impermeable plasma is a type of thermal plasma which acts like an impermeable solid with respect to gas or cold plasma and can be physically pushed. Interaction of cold gas and thermal plasma was briefly studied by a group led by Hannes Alfvén in 1960s and 1970s for its possible applications in insulation of fusion plasma from the reactor ...

  3. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Quark–gluon plasma is a very high-temperature phase in which quarks become free and able to move independently, rather than being perpetually bound into particles, in a sea of gluons, subatomic particles that transmit the strong force that binds quarks together. This is analogous to the liberation of electrons from atoms in a plasma.

  4. Plasma gasification - Wikipedia

    en.wikipedia.org/wiki/Plasma_gasification

    Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide. A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas , with slag [ 1 ] [ 2 ] [ 3 ] remaining as a byproduct.

  5. Saha ionization equation - Wikipedia

    en.wikipedia.org/wiki/Saha_ionization_equation

    With sufficient ionization, the gas can become the state of matter called plasma. The Saha equation describes the degree of ionization for any gas in thermal equilibrium as a function of the temperature, density, and ionization energies of the atoms. The Saha equation only holds for weakly ionized plasmas for which the Debye length is small ...

  6. Gas - Wikipedia

    en.wikipedia.org/wiki/Gas

    Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

  7. Atmospheric-pressure plasma - Wikipedia

    en.wikipedia.org/wiki/Atmospheric-pressure_plasma

    A discharge can be ignited and plasma can be sustained when a DC voltage that is delivered to the gas medium via electrodes is higher than the breakdown voltage for the gas. The relationship between this breakdown voltage and the pd product—where p is the gas pressure and d is the distance between the electrodes—is referred to as Paschen's law.

  8. Plasma globe - Wikipedia

    en.wikipedia.org/wiki/Plasma_globe

    A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.

  9. Induction plasma - Wikipedia

    en.wikipedia.org/wiki/Induction_plasma

    Induction plasma, also called inductively coupled plasma, is a type of high temperature plasma generated by electromagnetic induction, usually coupled with argon gas. The magnetic field induces an electric current within the gas which creates the plasma. The plasma can reach temperatures up to 10,000 Kelvin. Inductive plasma technology is used ...
