dew point-the temperature at which the water vapor in the air becomes saturated and condensation begins.temperature-the degree of hotness or coldness of a body or environment (corresponding to its molecular activity).ew point. The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.
The temperature at which air becomes saturated with water is called the air's dew point. This term makes sense, because water will condense from the air as dew, if the air cools down overnight and reaches 100% humidity. Figure 16.1: This diagram shows the amount of water air can hold at different temperatures.
