What is the relationship between temperature and saturation vapor pressure?
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 does saturation vapor pressure tell you?
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 to saturation vapor pressure when temperature 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.
Which of the following is the best indicator of the actual amount of water vapor in the air?
Dew point is a good indicator of the air’s actual water vapour content, unlike relative humidity, which takes the air’s temperature into account. High dew point indicates high water vapour content; low dew point indicates low water vapour content.
What is the relationship between saturation and temperature?
For a pure substance there is a definite relationship between saturation pressure and saturation temperature. The higher the pressure,the higher the saturation temperature. The graphical representation of this relationship between temperature and pressure at saturated conditions is called the vapor pressure curve.
What is the difference between saturation pressure and vapor pressure?
Saturation pressure is defined as the temperature at which the liquids start to boil at the given temperature. Vapour pressure is the measure of the tendency of the liquid to change into a vapour. It is the pressure exerted by the vapour in thermodynamic equilibrium on its condensed phase at a given temperature.
What is meant by 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 is vapor pressure related to temperature What happens to the vapor pressure of a substance when the temperature is increased decreased?
As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases.

| Saturation Vapor Pressure | describes how much water vapor is necessary to make the air saturated at any given temp. or it describes the maximum amount of water vapor the air can hold at a given time |
Which is a better indicator of the actual water vapor content in the air relative humidity or dew point temperature?
Rules of Thumb: The higher the dew point temperature, the greater the amount of water vapor is present (source for clouds). The smaller the difference between the temperature and the dew point temperature, the higher the relative humidity (the closer the atmosphere is to a state in which water vapor would condense).
What is the difference between saturation temperature and saturation pressure?
Saturation pressure is the pressure for a corresponding saturation temperature at which a liquid boils into its vapor phase. Saturation pressure and saturation temperature have a direct relationship: as saturation pressure is increased, so is saturation temperature.
