plsmas

Plasmas, often referred to as the fourth state of matter, are ionized gases. This means that a significant portion of the atoms or molecules within the plasma have lost or gained electrons, resulting in a collection of charged particles. These charged particles, including ions and free electrons, allow plasmas to conduct electricity and respond to electromagnetic fields. Plasmas can occur naturally, such as in stars, lightning, and the Earth's ionosphere, or they can be created artificially in laboratory settings and industrial applications. The properties of a plasma depend on factors like temperature, density, and the degree of ionization. High-temperature plasmas, like those found in stars, are very different from low-temperature plasmas used in technologies such as fluorescent lights and plasma televisions. The study of plasmas is known as plasma physics.
