Answer: At a certain temperature, when the vapor and liquid phases are in dynamic equilibrium, this state is also referred to as a saturated state. The vapor phase at this point is called saturated steam, and the pressure exerted by the steam is known as the saturated vapor pressure. The liquid phase at this point is called a saturated liquid, and the corresponding temperature is called the saturation temperature. http://bbs.hcbbs.com/static/image/hrline/4.gif Petrochemical Zone—New Ideas for Energy Saving: The “Creative Thinking” Campaign (Sponsors sought; highest returns ever offered) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event coordinator.

At a certain temperature, the steam rising from the material is equal to the liquid falling downward

The vapor phase at this point is called saturated steam, and the pressure exerted by the steam is known as the saturated vapor pressure.
The pressure at which the gas and liquid phases reach dynamic equilibrium at a certain temperature
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.
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 substance coexist. At this point, the evaporation and condensation processes reach dynamic equilibrium.
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 exerted by the vapor when a liquid is in equilibrium with its vapor at a certain temperature is known as 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
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. At this point, the evaporation/condensation process reaches dynamic equilibrium.
At a certain temperature and pressure, the rate at which a substance in its liquid phase evaporates into the gas phase is equal to the rate at which it liquefies in the gas phase; this pressure is known as the saturated vapor pressure
