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.
Plasma | Physics, State of Matter, & Facts | Britannica
WEBplasma, 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.

WEBMay 5, 2016 · 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...
DOE Explains...Plasma | Department of Energy
WEBTherefore, plasma is an ionized state made up of positively charged ions and negatively charged electrons. There are several reasons why electrons in atoms can separate and form plasma. In laboratory experiments, scientists can blast the atoms with high-voltage electricity, lasers, or electromagnetic fields to form plasma.

WEBPlasma 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.
Properties of Plasma - Chemistry LibreTexts
WEBJan 30, 2023 · A plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist. Plasma is the fourth state of matter. Many places teach that there are three states of matter; solid, liquid and gas, but there are actually four.
