Sorry for my unclear question... I am struggling with understanding what reversible/irreversible changes are for an ideal gas. Is it the change that keeps the ideal gas law during the change? Is any reversible change a sum of changes satisfying the ideal gas law (PV=nRT)? If so, it looks to me like any change is reversible if it is done very slowly.

    $\begingroup$ The concept of ideal gas has no bearing on this whatsoever. You are right, though, in that the changes which are done very slowly tend to be reversible. $\endgroup$ Dec 7 '21 at 16:20

  • $\begingroup$ thank you. Because the word "reversible" always comes with another word "isothermal" in my textbook, I was initially under impression that all the reversible changes were isothermal ones. $\endgroup$
