  • Plasma (physics) - Wikipedia
    Plasma (from Ancient Greek πλάσμα (plásma) 'moldable substance') [1] is a state of matter that results from a gaseous state having undergone some degree of ionisation It thus consists of a significant portion of charged particles (ions and or electrons)
  • States of Matter: Plasma | Live Science
    Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently Like gases, plasmas have no fixed shape or volume, and are less dense than
  • Plasma | Physics, State of Matter, Facts | Britannica
    plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states
  • Plasma - Center for Science Education
    Plasma is an electrically charged gas Because plasma particles have an electrical charge, they are affected by electrical and magnetic fields This is the main difference between a gas and a plasma A plasma is created when one or more electrons are torn free from an atom of gas
  • Science Made Simple: What Is Plasma? - SciTechDaily
    Plasma is one of the four fundamental states of matter, alongside gases, liquids, and solids While most people don’t think about plasma in their daily lives the way they think about other states of matter, plasma constitutes 99% of the visible matter in the universe
  • What Is Plasma? | MIT Plasma Science Fusion Center
    Plasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas It comprises over 99% of the visible universe In the night sky, plasma glows in the form of stars, nebulas, and even the auroras that sometimes ripple above the north and south poles
  • About Plasmas and Fusion - Princeton Plasma Physics Laboratory
    For more than 70 years, the U S Department of Energy’s Princeton Plasma Physics Laboratory has been a leader in the science and engineering behind the development of fusion — a clean, safe, and virtually limitless source of energy
  • Plasma Science and Technology - Basics - What are Plasmas?
    Plasma consists of a collection of free moving electrons and ions - atoms that have lost electrons Energy is needed to strip electrons from atoms to make plasma The energy can be of various origins: thermal, electrical, or light (ultraviolet light or intense visible light from a laser)
  • Plasmas explained - Science Learning Hub
    Plasma is the highest energy state of matter It consists of a collection of free-moving electrons, positive ions and neutral particles Although it is closely related to the gas phase in that it has no definite shape or volume, it does differ in a number of ways: Plasma has a very high electrical conductivity
  • Plasma classification (types of plasma) | Plasma-Universe. com
    Plasmas are described by many characteristics, such as temperature, degree of ionization, and density, the magnitude of which, and approximations of the model describing them, gives rise to plasmas that may be classified in different ways
