Plasma (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 any combination of ions or electrons.
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 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...
In 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.
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.
Plasma can consist of ions, electrons, or protons. Examples of plasma include lightning, the aurora, the Sun, and the inside of a neon sign. Bose-Einstein condensate (BEC) is sometimes called the fifth state of matter.
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 is one of the four common states of matter - solid, liquid, gas, and plasma. Plasma is an electrically charged gas. Because plasma particles have an electrical charge, they are affected by electrical and magnetic fields.
plasma, 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 (see ionization). Plasma is sometimes called the fourth state of matter (the first three being solid, liquid, and gas).
Plasma is the most abundant state of matter in the universe. Unlike solids, liquids, and gases, plasma consists of free electrons or ions that aren’t bound to an atomic nucleus. Plasma displays properties that distinguish it from other states of matter. Because it consists of charged particles, plasma has innate electrical conductivity.
