Adiabatic System

Postby Joyce Gu 1E » Sat Mar 17, 2018 5:36 pm

Since is no entropy change in an adiabatic process, there is no heat being transferred. Would that mean that an adiabatic process is always considered reversible?

I believe you are correct, as to my understanding energy in this process is only transferred as work.

Doesn't necessarily mean it is always reversible, but it will always be transferred as work because q=0.

Yeah I wouldn't assume that it is always reversible.

Even if you assume it is adiabatic and q=0, you cannot figure out whether it is reversible or irreversible without more information, such as if pressure or volume is constant or not. It also depends on whether the system is closed, open, or isolated.

Adiabatic does not mean that the system is necessarily irreversible or reversible. It simply means that q=0 because there is no change in temperature. This means that the change in internal energy is solely dependent upon work.
