70% to pass

The dew point temperature is _______________.

A always higher than the air temperature
B the temperature at which the air is saturated with water vapor
C equal to the difference between the wet and dry bulb temperatures
D always lower than the air temperature
AI Explanation

The correct answer is B) the temperature at which the air is saturated with water vapor. The dew point temperature is the temperature at which the air becomes saturated with water vapor, meaning the air can no longer hold any more water. At this temperature, water vapor starts to condense and form dew or other forms of precipitation. This is the fundamental definition of dew point temperature. The other options are incorrect because: A) the dew point temperature can be higher or lower than the air temperature depending on the humidity levels, C) the dew point is not related to the difference between wet and dry bulb temperatures, and D) the dew point temperature can be higher or lower than the air temperature.
