Fisica Plasma
In fisica e chimie, plasma es un statu de materie similar a gas in quel un portion significant del particules es ionisat.
Li basic premisse es que calentar un gas desassocia su ligantes moleculari, rendir it ad-in su atomes constituent. Additional calentation causa ionisation (un perde o ganie de electrones) del atomes, transformar li gas ad-in un plasma de particules chargeat: iones positiv e electrones negativ.
Li presentie de un numere innegligibil de portatores de charge fa li plasma conductiv electricmen, talmen it responde fortimen a campes electromagnetic. Plasma, ergo, ha proprietas tre diferent a tis de solides, liquides, o gases, e it es considerat un distint statu de materie. Quam gas, plasma ne have un forme o volume definit, si it ne es include in un recivuore; diferent de un gas, plasma conforma al influentie de un campe magnetic, e it posse formar structuras quam filamentes e radies. Alcun comun plasmas include stelles e signes de neon. In li universe, plasma es li max comun statu de materie por materie ordinari, li majori parte de quel es in li rarificat plasma intergalaxic (particularmen inter gruppes galaxic) e in stelles.
