    • n dew-point The temperature indicated by the thermometer when dew begins to be deposited; that temperature of the air at which the moisture present in it just saturates it. See saturation. The more humid the atmosphere, the less the difference between its temperature and that of the dew-point, and vice versa. When the air is saturated with moisture and any colder body is brought into contact with it, deposition of moisture or dew immediately takes place on its surface. See hygrometer.
