to change dew point, humidity must be changed. an increase in humidity will result in a higher dew point and vice versa.

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

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.


At what temperature would ice crystals form from air that has a dew point temperature of -6 degrees Celsius?

Ice crystals would form when the temperature of the air drops to 0 degrees Celsius or below. Since the dew point temperature is -6 degrees Celsius, the air would need to cool further to reach the freezing point of water and allow ice crystals to form.


Why is there dew in the morning?

We only see dew in the morning because of the way dew forms. For dew to form, air must be cooled to its condensation point. There must be little movement to the air or it will remain mixed and not form dew, but will form fog instead. (Fog is formed in other ways as well). These conditions usually occur overnight, when the winds die down, and the air becomes still. Radiational cooling from the ground or structures near the surface, such as automobiles, mailboxes, etc. cools the air in contact with the ground or structures. The humidity in the air condenses into droplets of moisture we call dew. After sunrise, the ground begins warm up and usually the wind increases. Both these events warm the air and evaporate the dew.


What is a psycrometer?

This is an instrument used to measure the relative humidity in the air.[Another way of determining this is to measure the dew point of the air. The temperature at which dew will form on a clean mirror that can be chilled. ]


What happens when air is saturated with water?

When air is saturated with water, it has reached its maximum capacity to hold water vapor at a given temperature. Any additional water vapor added will result in condensation - where the water vapor turns into liquid water, such as in the form of dew or precipitation.

What are two ways that air can be saturated?

one is lower the temperature to its dew point,and the other way is to eave the water out to evaporate.
