Question
Differentiate between the reversible and irreversible processes.

Answer
| Sr. No. | Reversible process | Irreversible process |
| i. | A reversible process is a change that can be retraced in a reverse (opposite) direction. | An irreversible process is a change that cannot be retraced in a reverse (opposite) direction. |
| ii. | The path of a reversible process is the same in the forward and the reverse direction. | The path of an irreversible process is not the same in the forward and the reverse direction. |
| iii. | Reversible changes are very slow and there is no loss of any energy in the process. | There is a permanent loss of energy from the system due to friction or other dissipative forces in an irreversible process. |
| iv. | The system comes back to its initial state after it is taken along the reverse path. | The change of state depends upon the path taken to change the state during an irreversible process. |
| v. | Reversible processes are ideal processes. | Irreversible processes are real processes. |
| vi. | p-V diagram: |
