trioxidestriplet state
triple point
The point in a one-component system at which the temperature and pressure of three phases are in equilibrium. If there are Math - ei possible phases, there are Math - ei triple points. Example: In the sulfur system four possible triple points (one metastable) exist for the four phases comprising rhombic S (solid), monoclinic S (solid), S (liquid) and S (vapour).
