Triple Point

Subject: Chemistry

Book: General Chemistry

The triple point on a phase diagram is the specific temperature and pressure at which a substance simultaneously exists in solid, liquid, and gaseous states in equilibrium. For water, this is ~0.01 °C and 0.006 atm. The triple point is unique for each substance and is important for precise temperature calibration and understanding phase transitions.
