Is work done in adiabatic process quasi static or not?

Click For Summary
SUMMARY

In thermodynamics, the work done in an adiabatic process is contingent upon the nature of the process. A reversible adiabatic process is classified as quasistatic, meaning all work is performed quasistatically. Conversely, in irreversible adiabatic processes, such as free expansion, work is either done rapidly and thus not quasistatic or not done at all. Understanding these distinctions is crucial for accurate thermodynamic analysis.

Welcome to PF!

What kind of adiabatic process are you speaking about? A reversible adiabatic process is quasistatic so any work is done quasistatically. In some irreversible adiabatic processes, work is done but it is done quickly, so it is not quasistatic. In some irreversible adiabatic processes, such as a free expansion of a gas, no work is done at all.
