I thought plasma was the most energetic state of matter, and that heat is proportional to energy levels? How is it possible for cold plasma then?
It's real plasma in the screen, real as in electrically charged gas. Plasma may seem like an exotic material, but it's really quite common.As I recall, any highly ionized gas can be called a plasma, and what's that stuff in plasma tvs?
As far as I know, the plasma of an electric discharge is the same that of an ionized gas. When the electrons go through, they eject electrons from the gas. You would not see anything if the electrons were alone. The glow you see from a van der Graaf is the same as aurora borealis or lightning, or a static discharge spark, all ionized gas.nightcleaner said:The word Plasma may also be used to describe a more fundamental grouping of particles, such as the electron flux in a spark discarge, whethor from a Van de Graff generator or from any other generator, battery, etc. This type of plasma involves only electrons (or other fundamental particles) and is not made up of atoms at all.
Nice reasoning, but I would need a reference to be convinced that biological plasma specifically refers to the electric charges.nightcleaner said:Plasma then in general refers to a gas or liquid which carries charged particles.
