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.
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.
Plasma 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.
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.
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.
3 maj 2016 · A plasma is what you get if you heat matter until it breaks apart into a gas of charged particles. It is, perhaps, the ultimate many-body system, as long-range interactions make possible...
After solid, liquid, and gas, plasma is the fourth state of matter. It is made of particles that have been ionized. This means the particles have been given so much energy that electrons separate from their atoms, making a subatomic soup. Unlike gas, plasma easily conducts electricity.
