Air: Source of Atmospheric Gases
Composition of air, source of the industrial gas products nitrogen, oxygen, argon, neon, krypton and xenon. Effects of temperature, humidity, elevation and trace components on properties of air and on air compression and separation processes.  Links to physical properties tables, to psychrometric charts that  depict inter-relationships among the various physical properties of air, to online psychrometric properties calculators for easy calculation of properties, and to individual gas information pages.  Includes discussion of the carbon dioxide concentration in air, seasonal variation, year-to-year variation, longer term variation over recent and geological time scales.
