The triple point of a substance is a unique temperature and pressure at which the three phases (solid, liquid, and gas) of that substance can coexist in thermodynamic equilibrium. This point is represented by a single point on a phase diagram.
The temperature point at which solid, liquid and gaseous states may stay together is known as
