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.
11 wrz 2022 · Learn what the triple point is and how it applies to water and other substances. Find the triple point values for common substances in a table and see how they vary with temperature and pressure.
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.
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.
12 lip 2023 · The triple point is −56.6°C and 5.11 atm, which means that liquid CO 2 cannot exist at pressures lower than 5.11 atm. At 1 atm, therefore, solid CO 2 sublimes directly to the vapor while maintaining a temperature of −78.5°C, the normal sublimation temperature.
Definition. 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.
