Web2 feb. 2011 · The humidity of a gas may be measured by a variety of techniques. Some are based on the determination of the partial pressure of vapor in the gas (e.g., dew point determination); the relationship between humidity and partial pressure is given in the entry entitled Humidity. WebThe dew point is the temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content.When cooled below the dew point, moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. When this occurs via contact with a colder surface, dew will form …

WebAbsolute humidity is the measure of the amount of water vapor in air. Relative humidity tells how much water vapor is in the air relative to the amount it has the potential to hold at a given temperature and pressure.
