What term describes the temperature at which condensation begins?

The term that describes the temperature at which condensation begins is known as the dew point. This is the temperature to which air must be cooled for water vapor to condense into liquid water. At or below this temperature, the air becomes saturated with moisture, and any further cooling leads to the formation of dew, fog, or clouds.

In contrast, humidity refers to the amount of moisture in the air but does not specify the temperature at which condensation occurs. The boiling point is the temperature at which a liquid turns into vapor, and the freezing point is when a liquid becomes solid; neither relates to the condensation process. Thus, the dew point is a key concept in meteorology for understanding humidity and weather patterns.
