What is triple point?
The temperature and pressure at which a substance can exist in equilibrium in solid, liquid and gaseous state.
The triple point of water was used to define the kelvin, the base unit of thermodynamic temperature for SI units.
Condition of triple point is 273.16 K ( 0.01 C ),
611.73 pascal.
