Plasma is one of the four basic states of matter among solid, liquid, and gas. Thermal plasmas reach higher temperatures as well as reach thermal equilibrium. hot plasmas are created by heating a gas until electrons have reach an energy that break free from the atoms.
Filaments are incorrectly seen to be of plasma, however, particles move in only one direction in them, often against gravity. In this non-thermal (fifth-) state of matter, particles have up to 10 16 -times higher energy than those in the hottest stellar plasma.
