Irreversibility
Second Law of Thermodynamics
Practically, all thermodynamic processes are irreversible process.
IRREVERSIBILITY Practically, all thermodynamic processes are irreversible process. When any process is reversed, it will definitely not follow the same path as the original process. At the same time, it produces a change in the universe. So, the path traced by the reverse process is different. Therefore, the work involved due to this process is called irreversible work. Irreversibility is produced due to various reasons. Causes of irreversibility: 1. Lack of equilibrium. 2. Heat transfer through a finite temperature difference. 3. Lack of pressure equilibrium within the interior of the system. 4. Free expansion. 5. Dissipative effects.
