What Is a Nonadiabatic Process? 2024 - Ablison

Web2 days ago · Adiabatic - Reversible and Irreversible process. Reversible Adiabatic Process. A reversible adiabatic process is basically an isentropic process. What is an Isentropic Process? Since in an adiabatic process, the heat transfer is zero which means the change in entropy is also zero. That’s why the process is said to be isentropic by nature.
