Atmosphere Thermal and Mechanical Equilibrium
 
 
 

We previously discussed the new conditions for thermal equilibrium in closed systems. Thermal  Equilibrium in Closed Systems 

Now consider a region of our atmosphere which is in thermal equilibrium: This now means that over a specified time frame:

1)      The polyatomic gas molecules absorb as much blackbody/thermal radiation, as they radiate, hence maintain a constant vibrational energy (atmosphere is mainly diatomic gases), which is a function of temperature.

2)      The gas molecules experience inelastic intermolecular collisions hence obey conservation of momentum and this means that pressure is conserved.! Hence inelastic collisions means that thermal/blackbody radiation is given off during collisions in order for energy to be conserved, and this radiation becomes part of the above described 1)!

3)      The gas molecules equally (give vs take) exchange vibrational energy with each other. In general net flow of vibrational energy in any direction will be zero. 

 

 

 

 Remember

 

Our atmosphere is the mother of all heat baths

 

Forms of work during expansion:

    It took work to form our atmosphere, hence it takes work to displace our atmosphere this can take two forms:

  1) Lost Work

   2) Negative Work
