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.
20 mar 2023 · The triple point is a thermodynamic term that refers to a specific combination of temperature and pressure in which three phases of a substance coexist in equilibrium. At the triple point, the substance can exist in all three states: solid, liquid, and gas.
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.
Definition. The triple point is a unique condition at which three phases of a substance (solid, liquid, and gas) coexist in thermodynamic equilibrium.
At the triple point, all three phases of a substance can exist simultaneously and can change into one another without altering the temperature or pressure. Each substance has its own unique triple point, which is determined by its specific properties and interactions at the molecular level.
