Plasma – Forth State of Matter

Plasma refers to hot ionized gas containing about equal number of negatively charged electrons and positively charged ions. Plasmas characteristics vary considerably from those of normal neutral gases such that plasmas are regarded as a distinctive fourth matter state. However, plasma behavior is highly comparable to that of a gas since plasma contains no defined volume but it instead assumes the containers volume. It also has pressure and density just like gases do. Irrespective of all the essential particles being charged, plasma typically contains no overall charge. Nevertheless, some non-neutral plasma can be generated with a general charge negative or positive and are comprised of pure antiproton, positron, ion, or electron plasmas. Plasmas contain particles that are electrically charged, and hence they are strongly impacted by magnetic and electric fields whereas neutral gases are not. Plasma also traps particles that are energetically charged in geomagnetic field lines to create the Van Allen radiation belts. The plasma magnetic and electric fields can impact plasma over big distances, shaping, warping, and pinching them as in the large, twisting flares perceived on the sun surface. Plasma is applied in various cases in real life situation. This include application in plasma in daily life include use in display TV, and lighting in various places, and welding among others. Plasma is also used to create laser energy which is used for various applications including printing.  There is continuing research on plasma with high probability of advance discovery in its use and application. Advance research creates a possibility of discovering more light related technology using plasma energy especially in compact accelerators.
