What is saturated vapor pressure? Answer: At a certain temperature, when the gas and liquid phases are in dynamic equilibrium, it is called a saturated state. The gas phase in this state is known as saturated vapor, and the pressure exerted by the saturated vapor is referred to as 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 known as the saturated vapor pressure
At a certain temperature, when the gas and liquid phases are in dynamic equilibrium, it is called a saturated state. The gas phase in this state is referred to as saturated vapor, and the pressure exerted by the saturated vapor is known as the saturated vapor pressure.
Vapor pressure refers to the partial pressure of the vapor produced by the vaporization of a liquid within a system. The vaporization of a liquid cannot continue indefinitely; there is a balance between vaporization and condensation – that is, while the liquid can vaporize, the resulting vapor also condenses at the same time. When the rate of vaporization is greater than that of condensation, vaporization occurs overall and the vapor pressure increases. When these two rates are equal, equilibrium is reached and the vapor pressure no longer increases. Under certain conditions, every reversible process tends to reach equilibrium; the maximum vapor pressure at this equilibrium point is known as the saturated vapor pressure. If the pressure of the liquid is lower than the saturated vapor pressure, vaporization will continue; if it is higher, the vapor will condense
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, when a liquid is in equilibrium with the vapor above its surface, the pressure exerted by the vapor is called the saturated vapor pressure
Under sealed conditions, at a certain temperature, the pressure of the vapor that is in phase equilibrium with a liquid or solid is called the saturated vapor pressure
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.
At a certain temperature, when the gas and liquid phases are in dynamic equilibrium, we call it a saturated state. The gas phase at this point is called saturated steam, and the pressure exerted by the steam is known as the saturated vapor pressure
It refers to the gas pressure (partial pressure) at a given temperature, when the liquid and gas phases of a certain substance coexist in a closed space. At this point, the evaporation and condensation processes reach dynamic equilibrium.
Under sealed conditions, at a certain temperature, the pressure of the vapor that is in phase equilibrium with a liquid or solid is called the saturated vapor pressure
