A process which cannot be retraced is:
Correct answer: A. Irreversible
- A. Irreversible
- B. Reversible
- C. Either a or b
- D. Cyclic
Explanation
An irreversible process is one that cannot be retraced or undone. In such processes, entropy always increases and the system and surroundings become increasingly disordered.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
