Plasma is one of the four fundamental states of matter, alongside solid, liquid, and gas. It consists of ionized particles, meaning that some electrons are stripped away from atoms, resulting in a mixture of free electrons and ions. This state is commonly found in stars, including our Sun, where extreme temperatures and pressures create conditions for plasma to exist. In addition to its presence in celestial bodies, plasma is also utilized in various technologies on Earth, such as in fluorescent lights and plasma TVs. Understanding plasma is crucial for advancements in fields like nuclear fusion and space exploration, as it plays a significant role in the universe's dynamics.
