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.
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]
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.
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.
At the triple point, the three phases of a substance can exist simultaneously without any change in mass or energy, demonstrating thermodynamic equilibrium. The triple point is critical for defining temperature scales; for example, the Kelvin scale is defined using the triple point of water.
The triple point is the unique set of conditions at which all three phases (solid, liquid, and gas) of a substance coexist in thermodynamic equilibrium. It is specific to each substance and occurs at a precise temperature and pressure.
12 lip 2023 · To be able to identify the triple point, the critical point, and four regions: solid, liquid, gas, and a supercritical fluid.
