Atmosphere

In the air there are 4 main gases: (Percentage to PPM= x10000)
Nitrogen-78%
Oxygen-21%
Argon-1%
Carbon Dioxide-0.0383%
Depending on the energy, molecules show different behaviours. In increasing order;
Translational, molecule moving around as a whole; Rotational, molecule rotates; Vibrational, the
bonds in the molecule vibrate; Electronic, the…
