The "Triple Point" is a specific condition where three phases of a substance coexist in thermodynamic equilibrium. For example, in the case of water, the triple point occurs at a precise temperature and pressure where ice, liquid water, and water vapor can exist simultaneously. This unique point is crucial for defining the temperature scale in thermodynamics. The concept of the triple point is important in various scientific fields, including chemistry and physics. It helps in understanding phase transitions and is used in calibrating thermometers. The triple point of water is set at 0.01°C and 611.657 pascals, serving as a standard reference point.
