Bookmark or Share- Plasma | Physics, State of Matter, & Facts | BritannicaPlasma, 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 | Definition, Function, & Composition | Britannicaplasma, the liquid portion of blood. Plasma serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.
- plasma and plasma physics - Students | Britannica Kids | Homework HelpPlasma is sometimes called the fourth state of matter because plasmas possess remarkable properties not found in ordinary solids, liquids, and gases. Because the free electrons are extremely mobile, for example, plasmas are excellent conductors of heat and electricity.
- Nuclear Energy, Plasma Physics, Fusion Power - BritannicaFirst, the discipline of plasma physics has developed to the point that theoretical and experimental tools permit quantitative evaluation of many aspects of fusion reactor concepts. Second, and perhaps most revealing, the evolutionary improvement of plasma parameters has placed experiments at the threshold of energy breakeven, in which energy ...
- Plasma - Oscillations, Parameters, Interactions | BritannicaThe basic variables useful in the study of plasma are number densities, temperatures, electric and magnetic field strengths, and particle velocities. In the laboratory and in space, both electrostatic (charged) and magnetic types of sensory devices called probes help determine the magnitudes of such variables.
