What does saturation vapor pressure mean?

Asked by: Heather Aus

What do you mean by saturation vapor pressure?

Definition of saturation pressure

: the pressure of a vapor which is in equilibrium with its liquid (as steam with water) specifically : the maximum pressure possible by water vapor at a given temperature.

What is the difference between vapor pressure and saturation pressure?

DEFINITION: Fundamentally, vapor pressure is the partial pressure of liquid vapor (e.g. water vapor). Saturated vapor pressure is the vapor pressure which is in equilibrium with an open liquid surface. Therefore, it is also the pressure at which a liquid will vaporize for a given temperature.

What does saturation mean in water vapor?

Air that contains the maximum amount of water vapor for a given temperature and pressure is said to be saturated. Another way of saying the same thing is that the relative humidity is 100%.

What happens when saturation vapor pressure increases?

As the temperature rises, the saturated vapour pressure increases rapidly, and so does the density of the vapour, approaching that of the liquid. At a certain temperature the density of the vapour becomes equal to that of the liquid, and the vapour and liquid become indistinguishable.

What does saturated vapor mean in thermodynamics?

Definition of saturated vapor

: vapor at the temperature of the boiling point corresponding to its pressure and so incapable of being compressed or cooled without condensing — compare equilibrium sense 1c.

What is saturated Vapour pressure of a substance?

The vapor pressure of a system, at a given temperature, for which the vapor of a substance is in equilibrium with a plane surface of that substance’s pure liquid or solid phase; that is, the vapor pressure of a system that has attained saturation but not supersaturation.

What happens if pressure is lower than saturation pressure?

The substance is in the gas (superheated vapor) state if the pressure is less than the saturation pressure at the given temperature or if the temperature is greater than the saturation temperature at the given pressure.

What is the relationship between saturation vapor pressure and air temperature?

Lower temperatures are saturated with respect to water vapor at lower vapor pressures, while higher temperatures need higher vapor pressures to be saturated. Temperature is the primary factor determining water vapor saturation. In the graph of saturation vapor pressure vs.

What is the relationship between pressure and temperature to saturated vapor?

The relationship between temperature and saturation vapor pressure is not linear which means that the rate that saturation vapor pressure increases is not a constant rate as temperature increases. The saturation vapor pressure increases more rapidly as temperature increases.

What is the difference between saturation temperature and saturation pressure?

The temperature at which vaporization (boiling) starts to occur for a given pressure is called the saturation temperature or boiling point. The pressure at which vaporization (boiling) starts to occur for a given temperature is called the saturation pressure.

How does pressure affect saturation?

During a phase change process, pressure and temperature are obviously dependent properties, that is, saturation temperature increases with saturation pressure. A substance at higher pressures boils at higher temperature which benefits us to make pressure cooker, for example.

What does saturated vapor pressure depend on?

temperature

So far I understand that the saturated vapor pressure is the pressure exerted by a substance in liquid (or solid) vapor equilibrium, and that this pressure depends on the temperature of the system.

How do you find saturation vapor pressure?

Take the temperature of the system for which you want to determine saturation pressure. Record the temperature in degrees Celsius. Add 273 to the degrees Celsius to convert the temperature to Kelvins. Calculate saturation pressure using the Clausius-Clapeyron equation.

Does saturation vapor pressure decrease with altitude?

At higher altitudes, the atmospheric pressure is decreased. The vapor pressure is not decreased – it is not affected by atmospheric pressure.
