We normally hear of solid, liquid, and gas as the three states of matter; however, two other states also exist, viz. Plasma (4th state) and Bose-Einstein condensate (5th state). In this article, we will be studying and investigating some aspects of Plasma, which is the most abundantly present (99 %) in the visible universe. In other words, what we see at night in the form of glittering stars, the day lightning sun, auroras in the sky and nebulae, all glow as Plasma, which is basically a heating gas that consists of positively charged particles (ions) and negatively charged particles (electrons). Its applications vary from different fields like studying space science and astrophysics, microfluidics, electronic chips, biomedical engineering, etc.
