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.
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.
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.
Definition. 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 ...
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.
11 wrz 2022 · The triple point is the temperature and pressure at which three states of matter exist in equilibrium. The critical point is also a combination of temperature and pressure, but it is the end point of a phase equilibrium curve where a liquid and its vapor can coexist.
