Question
As air temperature cools to dewpoint temperature, relative humiditystays the sameincreasesdecreases
Solution
As air temperature cools to dew point temperature, relative humidity increases.
Here's why:
-
Dew point is the temperature at which air becomes saturated (100% relative humidity) and water vapor in the air begins to condense into dew.
-
As the air temperature cools, it can hold less water vapor.
-
If the amount of water vapor in the air stays the same, and the air temperature decreases, the relative humidity increases because the air is closer to being saturated.
-
Therefore, as air temperature cools to the dew point temperature, the relative humidity increases.
