What is the relationship between dew point temperature and air pressure?

∙ 9y ago
Dew point is the temperature at which the air reaches saturation. Warmer air can retain more moisture than cooler air. So, ignoring other factors such as pressure, when the temperature drops to the dew point temperature, the air becomes saturated and therefore, if there is actually moisture in the air (is there a cloud?), it will start to rain or snow.

∙ 11y agoThe dew point is the temperature at which the air would have to be cooled to become saturated without changing the amount of water vapor. The cooler the air, the less water vapor it can hold. Once the air cools to the dew point, any further cooling normally results in condensation taking place, where the excess water vapor falls out.

∙ 11y agothe relationship is because both are the same in a way that cannot be configured

How do water temperatures affect air pressure?
The lower the pressure then the lower the temperature that is required to make it boil. Water at the top of Mount Everest boils well below 100 degrees centigrade due to the lower atmospheric pressure.
What state of matter is calcium at boiling point temperature?
"Boiling point temperature" is an ambiguous phrase. Please provide specific temperature and pressure values.
Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
What is the temperature at boiling point?
.The temperature at boiling point depend up on the vapour pressure. For example water boils at 100 degrees in atmospheric pressure ie, at 1 bar. But same water can boil at 40 degree celcius at -0.9 bar. That is , at reduced pressure a liquid boils at reduced temperature.So the temperature at boiling point depend up on the vapour pressure .
What is the fiducial point on the kelvin temperature scale?
The triple point of water (where you can boil water yet not melt ice; this can only happen with the correct temperature and pressure)
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
What is the relationship between the temperature and dew point?
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
What is the relationship between air temperature and dew point temperature when dew occurs?
They are the same.
Relation between Dew point temperature and pressure?
There is none.
What is the relationship between air temperature and dew point temperature at ground level if it is foggy?
They are about the same.
What is the relationship between the triple point of water and the si unit for temperature?

What is the relationship between air temperature and dew point when condensation occurs?
They are the same.
How do water temperatures affect air pressure?

The density of water depends on its?
Pressure and temperature. Increasing the pressure increases the density. Increasing the temperature decreases the density between melting point and 4oC
What relationship would you expect to find between the air temperature and dew point temperature at ground level if an area is covered in fog?
The relationship that you expect to find between the air temperature and dew point temperature at ground level if the area is covered by fog is the temperatures of th air and the dew point would be very close in value.
What is the difference between Gay-Lussac's law and Pascal's principle?
The laws have not too much in common. Pascal's law belongs to fluid mechanics and it describes, how is the pressure transmitted through the fluid: a change in pressure at one point of a confined fluid causes an equal change at every other point of the fluid. Gay-Lussac's law is part of thermodynamics. It gives the relationship between pressure and temperature of a gas. Ratio of pressure and temperature is the same, when volume is kept constant.
What relationship would you expect to find between the air temperature and dewpoint temperature at ground level is the area is covered by fog?
The relationship that you expect to find between the air temperature and dew point temperature at ground level if the area is covered by fog is the temperatures of th air and the dew point would be very close in value.
