Plasma is the fourth state of matter, consisting of a gas that has been heated to extremely high temperatures and ionized to the point where it becomes conductive and exhibits electromagnetic properties. Plasma is often referred to as the "fourth state of matter" because it does not fit into the traditional categories of solid, liquid, or gas. It is found naturally in stars, lightning, and the auroras, and is also commonly used in various technologies such as plasma TVs, fluorescent lighting, and plasma welding. Plasma is considered to be a key element in the field of plasma physics and holds great potential for a wide range of applications in science, industry, and medicine.
