प्रश्न
What is meant by a reversible and irreversible processes?
Advertisements
उत्तर
Reversible processes: A thermodynamic process can be considered reversible only if it possible to retrace the path in the opposite direction in such a way that the system and surroundings pass through the same states as in the initial, direct process.
Irreversible processes: All natural processes are irreversible. Irreversible processes cannot be plotted in a PV diagram, because these processes cannot have unique values of pressure, the temperature at every stage of the process.
