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 air must be at or near its saturation point for condensation to take place. Air can become saturated in two ways, 1) add water to the air by evaporation thus bringing it to saturation given its present temperature, or 2) cool the air to its dew point temperature.Cooling the air is the most common way for condensation to occur and create clouds.ir can become saturated in two ways, 1) add water to the air by evaporation thus bringing it to saturation given its present temperature, or 2) cool the air to its dew point temperature.
