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] It is that temperature and pressure at which the sublimation , fusion , and vaporisation curves meet.
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.
Below the triple point, the substance can exist only as a solid or a gas, depending on the temperature and pressure. Above the triple point, the substance can exist only as a liquid or a gas. For example, the triple point of water is at a temperature of 0.01 degrees Celsius and a pressure of 611.657 pascals.
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.
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.
30 sty 2023 · Figure 1. General Phase diagram. Triple point – the point on a phase diagram at which the three states of matter: gas, liquid, and solid coexist. Critical point – the point on a phase diagram at which the substance is indistinguishable between liquid and gaseous states.
The triple point of a substance is the specific condition at which all three phases (solid, liquid, and gas) coexist in thermodynamic equilibrium. This unique set of temperature and pressure is crucial in understanding phase changes and forms an important point on phase diagrams, as it illustrates the delicate balance between different states ...
