Definition: Saturated vapor pressure. Answer: In any liquid, the molecules at its surface have a tendency to escape from the surface and enter the air, a process known as vaporization. Vaporization and condensation 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, a dynamic equilibrium is established between the vapor and the liquid. At this point, the vapor pressure above the liquid is the boiling vapor pressure of that liquid at that temperature. http://bbs.hcbbs.com/static/image/hrline/4.gif The petrochemical deep processing version – the event to share pictures of chemical equipment has started!

The pressure of a vapor that is in phase equilibrium with a solid or liquid at a certain temperature under sealed conditions is called the 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. The level of vapor pressure indicates the ability of molecules in a liquid to leave the liquid and turn into vapor or steam. The higher the vapor pressure, the easier it is for the liquid to vaporize. The magnitude of vapor pressure is primarily related to the temperature of the system; the higher the temperature, the greater the vapor pressure.

The pressure of a vapor that is in phase equilibrium with a solid or liquid at a certain temperature under sealed conditions is called the saturated vapor pressure. The same substance has different saturated vapor pressures at different temperatures, and these pressures increase as the temperature rises. The saturated vapor pressure of the pure solvent is greater than that of the solution ； For the same substance, the saturated vapor pressure in the solid state is lower than that in the liquid state.
The pressure exerted by the vapor in equilibrium with the liquid (or solid) form of the same substance is called the saturated vapor pressure, and it increases as the temperature rises.
Saturated vapor pressure refers to the gas pressure (partial pressure) of a substance in a closed space, at a given temperature, when its liquid phase and gas phase coexist.
