What are facts about plasma?

Answer 1

Plasma is that state of matter where the matter is totally ionized in the form of ions and electrons, and there is no interaction between the ions or electrons at such high temperatures. For an ionic state to occur in nature, a high amount of energy is needed, but in some cases, it can be low. Plasma is the most common state of matter in the universe. Examples of plasma include solar wind, lightning, the gases in neon signs, welding arcs, interstellar gas clouds and the tails of comets. Over 99% of the matter in the visible universe is believed to be plasma. Plasma is a better conductor of electricity than copper. Stars (including the Sun) are mostly made of plasma. Plasma is usually very hot because it takes very high temperatures to break the bonds between electrons and the nuclei of the atoms. On earth lightning and aurora make plasma. Artificial (man-made) uses of plasma include fluorescent lightbulbs, neon signs, and plasma displays used for television or computer screens. Scientists are experimenting with plasma to make a new kind of nuclear power, called fusion, which would be much better and safer than ordinary nuclear power, and would produce much less radioactive waste.
