In physics and chemistry, a plasma is typically an ionized gas, and is usually considered to be a distinct phase of matter in contrast to solids, liquids, and gases because of its unique properties. "Ionized" means that at least one electron has been dissociated from a proportion of the atoms or molecules. The free electric charges make the plasma electrically conductive so that it responds strongly to electromagnetic fields.

Plasma is considered a physical state of matter. Perhaps a better word would be a "phase" of matter.
In the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i.e. density, crystal structure, index of refraction, and so forth). The most familiar examples of phases are solids, liquids, and gases. Less familiar phases include: plasmas and quark-gluon plasmas; Bose-Einstein condensates and fermionic condensates; strange matter; liquid crystals; superfluids and supersolids; and the paramagnetic and ferromagnetic phases of magnetic materials.

A plasma is a aggregation of ionized gas and electrons and neutrals. It may not necessarily be hot, in which case iit is called cold plasma. A plasma can be produced, just by applying high voltage across a tube containing a gas that can be ionized at that voltage.

First of all, it's spelled "plasma." A plasma occurs when a gas becomes so hot that the electrons orbiting the nuclei gain enough kinetic energy to break away from their orbits. It's somewhat similar to a gas, but more of a "soup" of ionized atoms and free electrons.

Plasma is a state of matter where the atomic particles become so energized (in this case, typically from heat) that the subatomic particles separate, leaving only ionized protons-

Gases superheated to such an extent that they becomes ionised, i.e., lose electrons.
By the way, there are 5 states of matter; the 5th one being the Bose - Einstein Condensates.

well i use a plazma arch machine at work that cuts alloy steel;such as stainless steel, inconile,crome,aluminum and many more ,that's the plazma i know.

Plasma is a gas in which the gas particles have an electric charge.

Matter of fact, each time i turn on my plasma
TV and i have a plasma of a time. I know that's a stupid answer!!!
