What are the charact eristics of a plasma?

Plasma is a state of matter where gas is ionized, meaning it contains free electrons and positively charged ions. It is highly conductive, responds to electromagnetic fields, and emits light, often seen in phenomena like lightning and fluorescent lights. Plasmas typically occur at high temperatures, where sufficient energy is available to strip electrons from atoms. Additionally, plasmas are found in stars, including the sun, and are used in various technologies such as plasma TVs and fusion research.
