What is plasma, the fourth state of matter?

Question

Plasma is still mysterious because it has never been existed in the Earth. Actually, how can the scientist know about plasma? And by how?

Answer 1

Plasma, in physics, usually gaseous state of matter in which a part or all of the atoms or molecules are dissociated to form ions. Plasmas consist of a mixture of neutral particles, positive ions (atoms or molecules that have lost one or more electrons), and negative electrons. A plasma is a conductor of electricity, but a volume with dimensions greater than the so-called Debye length exhibits electrically neutral behavior. At a microscopic level, corresponding to distances shorter than the Debye length, the particles of a plasma do not exhibit collective behavior but instead react individually to a disturbance, for example, an electric field.

Answer 2

"never been existed" -- I disagree. Plasma has existed on Earth. And it's not particularly "mysterious" to the people who study it.

A plasma is just a gas made up of ions -- the atoms have had one or more electrons removed from them. Lightning is made of plasma. So are the aurora ("northern lights"). Man-made forms include plasma display TVs, fluorescent lamps, and neon signs.

Answer 3

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

Answer 4

gasoline vs. Vapor The be conscious vapor in its organic state is a sturdy or liquid at room temperature. although, a gasoline in its organic state at room temperature could nonetheless be a gasoline. occasion: a million) steam could be a vapor by using fact at room temperature, it may be water, that's a liquid. 2) Nitrogen (a gasoline) at room temperature could nonetheless be in a gaseous state. To make it extra basic, a vapor is a substance which has experienced slightly exchange. while, a gasoline is a substance which has no longer, and could no longer adventure slightly exchange. gasoline is a state of rely on an identical time as vapor isn't. A gasoline is a substance above its severe temperature yet below its severe tension, on an identical time as a vapor is a substance above its boiling element temperature. A vapor is a gasoline. To me, the be conscious, "vapor" shows a gasoline that exchange into shaped via evaporation of something it somewhat is a liquid at room temperature. as an example, water vapor. It additionally connotes a gasoline which would be considered.

Answer 5

Matter whose electrons have been stripped off is called PLASMA.

Answer 6

plasma is ionised gas obtained by high heating
