PPT-HUMIDITY Humidity  is the amount of 

water vapor  in the  air Humidity There are three main measurements of humidity absolute relative and specific Absolute humidity is the total amount of water vapour present in a given volume of air. Chapters 4 and 5. 1. Class #3 July 9, 2010. Atmospheric Humidity. Chapter 4. 2. Class #3 July 9, 2010. Circulation of Water in the Atmosphere. A general definition of humidity is the amount of water vapor in the air.. ABSOLUTE HUMIDITY:. Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature. The higher the amount (weight) of water vapor per kilogram, the higher the absolute humidity. . QUIZ. Review of Pressure Conversions. Humidity and Aerosol. Review. PAO2. P(A-a). CaO2. DO2. Pressure Conversions. Respiratory therapists use several different pressure measurement scales. We have already discussed conversion from gauge to absolute pressure. It is also important to be able to convert from one scale to another, . Some Basic Issues. And Methods. Causes of Deterioration. Temperature and Relative Humidity.. Atmospheric Pollutants.. Light..
