- PLASMA
-
- The fourth state of matter, in which some atoms are ionised, having lost one or more electrons. Thus plasma is gas
- consisting of positive ions and electrons, as well as neutral atoms. On Earth all matter is solid, liquid, or gas, with no
- plasma, except in the magnetosphere. But in a star the bulk of the matter is in the plasma state. Even after the big bang
- the original material of the universe was plasma, and still today the majority of the matter in the universe is plasma.
- Plasma is electrically conducting, which is why eruptions on the surface of the Sun are warped by the Sun's magnetic
- field.
