7 Ιουν 2016 · In principle, you can use the integrated Clapeyron and Clausius–Clapeyron equations to calculate $P$ vs. $T$ co-existence lines and find the crossing point which is at the triple point. You need the $\Delta H$ for fusion and evaporation and the densities of the solid and liquid phases.
The triple point temperature is denoted by T 3, and triple point pressure by P 3. More generally, the term triple point is used to describe the conditions under which any three phases of a substance can exist in equilibrium.
11 Σεπ 2022 · In chemistry and physics, the triple point of a pure substance is the combination of temperature and pressure where three phases exist in thermodynamic equilibrium. Usually, the triple point refers to the point where a substance’s solid, liquid, and vapor phase coexist in equilibrium.
18 Νοε 2019 · In chemistry and physics, the triple point is the temperature and pressure at which solid, liquid, and vapor phases of a particular substance coexist in equilibrium. It is a specific case of thermodynamic phase equilibrium.
25 Νοε 2010 · Triple point: The combination of the temperature and the pressure at which the three phases (gas, liquid, and solid) of a substance coexist in thermodynamic equilibrium. Triple point for some common substances:
The triple point is a key feature on a phase diagram as it marks the unique conditions where solid, liquid, and gas phases coexist. By identifying this point on the diagram, one can easily understand the relationships and transitions between different phases under varying temperatures and pressures.
In physics and chemistry, the triple point of a substance is the temperature and pressure at which three phases (gas, liquid, and solid) of that substance may coexist in thermodynamic equilibrium.
