triple point

Show Summary Details

Quick Reference

The point on a phase diagram at which planes or phases meet. This is the temperature and pressure at which the three phases (solid, liquid, and gas) of a substance can coexist (see also kelvin scale). In a solid-solution system, the triple point is usually defined by the original pressure and temperature conditions at which the solid, liquid, and gaseous phases of a substance are in equilibrium.
