Ionized gas, also known as plasma, is a state of matter where atoms have lost or gained electrons, resulting in charged particles. This phenomenon occurs under high energy conditions, such as in stars like the Sun or during lightning strikes on Earth. Plasma is the most abundant form of visible matter in the universe, making it crucial for understanding cosmic events. In everyday life, ionized gas is utilized in various technologies, including fluorescent lights and plasma TVs. The study of ionized gases is essential in fields like astrophysics and fusion energy, as it helps scientists explore the fundamental processes that govern the universe.
