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.
Usually in order for condensation to take place, the atmosphere must be fully saturated. In other words, the maximum vapor pressure must have been reached. In addition to being saturated, the nature of water requires that there be a surface upon which water can condense. This surface might be blades of grass or windows. In the atmosphere, condensation often takes place around dust particles or other particulates such as smoke and even microscopic bacteria.
