Question

Define reversible and irreversible actions and write one example of each.

✓

Answer

Reversible action : Such action after completion of which the system and its surroundings return to its original state, is called reversible action. In this process the remaining source and sink remain unaffected.
Example: carnot engine.
Irreversible action : Any action which is not reversible is called irreversible action. This cannot be done in the opposite direction.
Example : Conduction, radiation and so on.
