The triple point or any substance is the combination of temperature and pressure at which it exists in its solid, liquid, and gaseous state all at once, in equilibrium.. If enough moisture is wrapping in from the warm sector than big rains and storms can fire along the triple point and along the fronts and wrap into the low pressure. Triple point is represented by a point on p-T diagram but appears as a line on p-v-T surface. Thanks . Iron: α-γ-ε triple point 678 K 8.2 ± 0.1 GPa. The triple point of pure water is at 0.01°C (273.16K, 32.01°F) and 4.58 mm (611.2Pa) of mercury and is used to calibrate thermometers. It is the point at which all three lines meet. They are evaporation, condensation, fusion, freezing, sublimation, and deposition. Under these conditions the compound has been observed to boil, … It is called triple point because at a particular temperature and pressure for particular substances, solid, liquid, and vapor phases coexist in equilibrium or we can say that the point where liquid becomes stable is called the triple point. This agreement also sets the size of the kelvin as 1/273.16 of the difference between the triple-point temperature of water and absolute zero. Triple point definition: the temperature and pressure at which the three phases of a substance are in equilibrium... | Meaning, pronunciation, translations and examples The triple point is a special temperature where all three phases of matter for a single material can exist together. This is equivalent to 0.01oC and 32.02oF, and thus we use T3 to help set the freezing point of water. Triple point of water is 273 K temperature and 0.46 cm of mercury pressure. The cell now contains three phases of water in equilibrium - liquid, gas, and solid. Finally, consider an initial pressure of the ice of 0.08854 psia. The triple point of water is 273.16 K at 611.73 Pa. The triple point of a substance can be easily identified. In thermodynamics , the triple point of a substance is the temperature and pressure at which the three phases ( gas , liquid , and solid ) of that substance coexist in thermodynamic equilibrium .
