Plasma is the fourth state of matter, along with solid, liquid, and gas. It consists of ionized gas particles that are highly energized and exhibit unique properties, such as the ability to conduct electricity and respond to electromagnetic fields. Plasma research focuses on studying the behavior and properties of plasma, as well as its applications in various fields such as astrophysics, fusion energy, materials processing, and medical treatments. Plasma research also plays a crucial role in developing technologies like plasma TVs, plasma thrusters for spacecraft, and plasma sterilization methods.
