11. In a non-adiabatic process , there are indefinitely many paths between the initial and final states. 12. The adiabatic process for air has a characteristic temperature-pressure curve, so the process determines the lapse rate. 13. I'm given a cycle that consists of an adiabatic process , an isobaric process, and an isochoric process. 14. Put differently, because this is an adiabatic process , the work done on the system is the change in internal energy. 15. In thermodynamics, an adiabatic process is a change that occurs without heat flow, and slowly compared to the time to reach equilibrium. 16. It is now understood that same-symmetry intersections play as important a role in non-adiabatic processes as symmetry-allowed intersections. 17. Consequently no adiabatic process initiated at nonzero temperature can lead to zero temperature . " ( H " Callen, pp . 189 190) 18. If only adiabatic processes were of interest, and heat could be ignored, the concept of internal energy would hardly arise or be needed. 19. An adiabatic process is one where there is no heat transfer between the fluid and the surroundings : the system is insulated against heat transfer. 20. He considered pseudo-adiabatic processes describing air as it is lifted, expands, cools, and eventually condenses and precipitates its water vapor.
