Triple point. A typical phase diagram. The solid green line applies to most substances; the dashed green line gives the anomalous behavior of water. 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. [1]
18 lis 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. The term "triple point" was coined by James Thomson in 1873.
12 lip 2023 · To understand the basics of a one-component phase diagram as a function of temperature and pressure in a closed system. To be able to identify the triple point, the critical point, and four regions: solid, liquid, gas, and a supercritical fluid.
11 wrz 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.
24 lis 2022 · The triple point and the critical point. The only point in the \(PT\) diagram where all the three phases coexist is called the triple point. The number of degrees of freedom at the triple point for every 1-component diagram is \(f=1-3+2=0\).
Definition. The triple point of a substance is the specific temperature and pressure at which three phases (gas, liquid, and solid) coexist in thermodynamic equilibrium. This unique point is crucial in understanding phase equilibria and phase diagrams, as it provides a reference for the behavior of materials under varying conditions.
The triple point is a unique condition where three phases of a substance coexist in equilibrium at a specific temperature and pressure. It represents a critical state in phase diagrams, as it provides essential information about the transitions between solid, liquid, and gas phases of a material.
