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.
