Web2.5 Adiabatic Processes: The Path of Least Resistance. Adiabatic Process. So far, we have covered constant volume (isochoric) and constant pressure (isobaric) processes.There is a third process that is very important in the atmosphere—the adiabatic process.Adiabatic means no energy exchange between the air parcel and its environment: Q = 0.Note: … WebMay 22, 2024 · A throttling process is a thermodynamic process, in which the enthalpy of the gas or medium remains constant (h = const). In fact, the throttling process is one of isenthalpic processes. During the throttling process no work is done by or on the system (dW = 0), and usually there is no heat tranfer ( adiabatic) from or into the system (dQ = 0).
