Quizplus · Accepted Answer

Given 100% relative humidity, the temperature and dew point are equal. With a lapse rate of 5°C/km over 4000m, the temperature decrease would be 20°C. If the base temperature is not specified, assuming a standard lapse without a starting temperature, the focus is on the process: both temperature and dew point decrease equally in 100% humidity.
