20 wrz 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. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states.
Plasmas are studied by the vast academic field of plasma science or plasma physics, including several sub-disciplines such as space plasma physics. Plasmas can appear in nature in various forms and locations, with a few examples given in the following table:
Plasma is superheated matter that forms an ionized gas and comprises over 99% of the visible universe. Learn how plasma is created, how it behaves, and how it is used for fusion power and other applications at MIT PSFC.
9 lut 2019 · The term plasma comes from a Greek word that means jelly or moldable material. The word was introduced in the 1920s by chemist Irving Langmuir. Plasma is considered one of the four fundamental states of matter, along with solids, liquids, and gases.
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.
22 maj 2024 · Plasma, making up 99% of the visible universe, exists predominantly in stars and space. It forms when electrons detach from atoms, creating ions and free electrons, a state that can conduct electricity and exhibits complex behaviors.
Plasma is an ionized state of matter that makes up 99% of the visible matter in the universe. Learn how plasma forms, its types, and why it is important for fusion energy research from the Department of Energy.
