For a pure substance, under sealed conditions and at a certain temperature, the pressure of its vapor that is in phase equilibrium with its solid or liquid phase is known as the saturated vapor pressure of that substance at that temperature.
Saturated vapor pressure: In a closed space, at a given temperature, it is the gas pressure (partial pressure) when the liquid and gas phases of a certain substance coexist. At this point, the evaporation/condensation process reaches dynamic equilibrium.
It refers to the gas pressure at a given temperature, within a closed space, when the liquid and gas phases of a certain substance coexist. It is also known as Red vapor pressure.
In any liquid, the molecules on its surface have a tendency to break away from the surface and move into space, a process known as vaporization. At the same time, the spatial gas molecules generated also have a tendency to form a liquid due to their continuous motion, that is, liquefaction. Vaporization and liquefaction are two opposite processes that occur simultaneously. At a certain temperature, when the number of molecules that move into space equals the number of molecules that form the liquid, that is, when the relative amounts of vapor and liquid no longer change, a dynamic equilibrium is established between the vapor and the liquid. At this point, the vapor pressure above the liquid is the saturated vapor pressure of that liquid at that temperature.
At a certain temperature, a liquid is in equilibrium with the vapor above its surface, and the pressure exerted by this vapor is known as the saturated vapor pressure.
On the surface of a liquid, there are processes of transformation from liquid to gas, and from gas to liquid. When this gas-liquid transformation reaches equilibrium, the pressure at that point is the saturated vapor pressure of that liquid at that temperature.
What is saturated vapor pressure? At a certain temperature, when a liquid is in equilibrium with the vapor above its surface, the pressure exerted by the vapor is called the saturated vapor pressure, or simply vapor pressure.
Saturated vapor pressure refers to the gas pressure (partial pressure) in a closed space, at a given temperature, when the liquid and gas phases of a certain substance coexist.
The pressure of a vapor that is in phase equilibrium with a liquid or solid at a certain temperature under sealed conditions is called the saturated vapor pressure.
The pressure at which gas-liquid equilibrium is reached at a certain temperature
