We know three states of the matter; solid, liquid and gas, BUT, what is a plasma?

Answer 1

its electromagnetic...

Plasma is the fourth state of matter. Many places teach that there are three states of matter; solid, liquid and gas, but there are actually four. The fourth is plasma. To put it very simply, a plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist. The funny thing about that is, that as far as we know, plasmas are the most common state of matter in the universe. They are even common here on earth. A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus. Gases can become plasmas in several ways, but all include pumping the gas with energy. A spark in a gas will create a plasma. A hot gas passing through a big spark will turn the gas stream into a plasma that can be useful. Plasma torches like that are used in industry to cut metals. The biggest chunk of plasma you will see is that dear friend to all of us, the sun. The sun's enormous heat rips electrons off the hydrogen and helium molecules that make up the sun. Essentially, the sun, like most stars, is a great big ball of plasma.

a collection of charged particles (as in the atmospheres of stars or in a metal) containing about equal numbers of positive ions and electrons and exhibiting some properties of a gas but differing from a gas in being a good conductor of electricity and in being affected by a magnetic field ,,, a display (as a television screen) consisting of discrete cells of plasma sandwiched between two layers of glass and electrodes such that each cell emits light when it receives an electric current



Plasmas are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects. Further, plasmas carry electrical currents and generate magnetic fields. Plasmas are the most common form of matter, comprising more than 99% of the visible universe, and permeate the solar system, interstellar and intergalactic environments.

Plasmas are radically multiscale in two senses
(1) most plasma systems involve electro-dynamic coupling across micro-, meso- and macroscale and (2) plasma systems occur over most of the physically possible ranges in space, energy and density scales. The figure here illustrates where many plasma systems occur in terms of typical densities and temperatures.

Because plasmas are conductive and respond to electric and magnetic fields and can be efficient sources of radiation, they can be used in innumerable applications where such control is needed or when special sources of energy or radiation are required.

i am right,,,

Answer 2

I think that what plasma is has been answered pretty well so far. I would like to add that there are other states of matter besides the big three mentions. Liquid crystals, such as those found in LCD watches, are not exactly liquid or solid crystals, but a hybrid state of the two.

Glass is another oddity in that is officially lies in between the solid and liquid phases. Think of it as a slow-moving liquid that had the resistance to change shape as of a solid.

Also, there are varying states with the list given above. Graphite and diamond are technically two different states of matter. Indeed, at standard room temperature and pressure, graphite is the thermodynamically stable version and we have diamond only because it takes a really long time for it change over to graphite.

Just FYI.

Answer 3

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. "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.

This fourth state of matter was first identified in a discharge tube (or Crookes tube), and so described by Sir William Crookes in 1879 (he called it "radiant matter")[1]. The nature of the Crookes tube "cathode ray" matter was subsequently identified by English physicist Sir J.J. Thomson in 1897[2], and dubbed "plasma" by Irving Langmuir in 1928 [3], perhaps because it reminded him of a blood plasma [4]. Langmuir wrote:

"Except near the electrodes, where there are sheaths containing very few electrons, the ionized gas contains ions and electrons in about equal numbers so that the resultant space charge is very small. We shall use the name plasma to describe this region containing balanced charges of ions and electrons."[3]
Plasma typically takes the form of neutral gas-like clouds or charged ion beams, but may also include dust and grains (called dusty plasmas). [4] They are typically formed by heating and ionizing a gas, stripping electrons away from atoms, thereby enabling the positive and negative charges to move freely.

Answer 6

Plasma is a state all of it's own... Can't really consider it a liquid, solid, gas, or sublimination because the temperature is causing all those different reactions to occure, therefore making a stable state impossible.

Answer 7

Plasma: An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. It is a phase of matter distinct from solids, liquids, and normal gases.

Answer 8

It's the fourth state of the matter, and is found mainly in the universe, inside stars and other celestial bodies. It's a mixture of solid particles and gas inside liquid, a form of a cocktail of the other three.

Answer 9

When temprature increases we have:

solid > liquid > gas > plasma

Plasma`s viscosity is higher than gas, you can find the reason by viscosity equasions.

I think in TVs its not plasma but some kind of polymer.

Answer 10

actually there r 5 states of matter: solid, liquid, gas, plasma n bos-einstein condensate.
plasma is the fourth rare state of matter. it is the ionised gas having charges
