Plasma (physics) - Wikipedia
WEBPlasma (from Ancient Greek πλάσμα (plásma) 'moldable substance' [1]) is one of four fundamental states of matter (the other three being solid, liquid, and gas) characterized by the presence of a significant portion of charged particles in …
What is Plasma? | MIT Plasma Science and Fusion Center
WEBPlasma 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.

WEBSep 7, 2024 · 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.
WEB1.1 What is a Plasma? 1.1.1 An ionized gas A plasma is a gas in which an important fraction of the atoms is ionized, so that the electrons and ions are separately free. When does this ionization occur? When the temperature is hot enough. Balance between collisional ionization and recombination: Figure 1.1: Ionization and Recombination
Plasmas explained - Science Learning Hub
WEBPlasma is more readily influenced by electric and magnetic fields than by gravity; The motion of electrons and ions in plasma produces its own electric and magnetic fields. Because of the totally chaotic and highly energetic state of the constituent particles of plasma, it produces its own electromagnetic radiation.

DOE Explains...Plasma | Department of Energy
WEBIn plasma, some of the electrons separate and become free from neutral atoms (atoms that have an equal number of protons and electrons and thus a neutral charge). The resulting free electrons makes plasma different from the other states of matter, where the electrons are held close to nuclei .
About Plasmas and Fusion - Princeton Plasma Physics Laboratory
WEBPlasma is a state of matter along with solids, liquids and gases. When a neutral gas is heated such that some of the electrons are freed from the atoms or molecules, it changes state and becomes a plasma. It consists of a partially-ionized gas, containing ions, electrons, and neutral atoms.
