Ponch Critic
Lo ponch critic d'un còrs pur es lo ponch dau diagrama temperatura-pression, generalament notat C, onte s'arrèsta la corba d'equilibri liquid-gas.
Es definit per una temperatura critica TC e per una pression critica PC. En delà d'aqueu ponch, es pas possible d'observar de cambiament d'estat liquid-gas e lo fluid es dich supercritic.
