TermDefinition
water vapor A gas in the atmosphere. 1% - 4% of the atmosphere. We wouldn't have clouds, rain or snow without it. It is a greenhouse gas which helps trap the earth's heat.
condensation Change of water vapor to liquid water, as when fog or dew forms.
saturated air Air that contains the maximum amount of water vapor it can hold at its temperature and pressure.
relative humidity Ratio of water vapor in the air compared to max amount of moisture the air can hold at that specific temperature & pressure.
dew point Temperature at which water starts to condense out of a particular air mass. Changes only when the moisture content of the air changes. Higher the dew point/greater the moisture content.
saturation point same as dew point
humidity Amount of water vapor in the air.
