not a state of matter, it is an ionized gas. We use it in the
lab in ICP-(AES, MS, etc), or, inductively-coupled-plasma -
(atomic emission spectrum, mass spec, etc), the plasma is
ionized argon, with the flame temp from 6000-10000 degrees is
not a state of matter tho. The fourth 'common' one, other than
solid, liquid, gas, is known as a superfluid, when the
temperature and pressure reach a certain 'supercritical point',
beyond which the compound forms a superfluid, with all kinds of
cool properties. My 1st year chem prof does the majority of
research on them, mainly using them as solvents to treat
environmental contamination, drug delivery, among others
(sometimes they work, sometimes they dont, but superfluid CO2 is
really nifty, gotta say!) Hope that clears some things up :)
