Detailed explanation-1: -Plasma physics is concerned with the study of highly ionized gases-that is, gases that have been separated into positively and negatively charged particles.
Detailed explanation-2: -The fully ionized gas is regarded as the fourth state of matter, existing for conditions where the kinetic energy of the atoms, molecules or electrons (as appropriate) exceeds the characteristic binding energy of the three other states, solid, liquid and gas1.
Detailed explanation-3: -Plasma is often called “the fourth state of matter, ‘’ along with solid, liquid and gas. Just as a liquid will boil, changing into a gas when energy is added, heating a gas will form a plasma – a soup of positively charged particles (ions) and negatively charged particles (electrons).
