1.	In thermodynamics, a process is called reversible whenA. Surroundings and system change into each otherB. There is no boundary between system and surroundingsC. The surroundings are always in equilibrium with the systemD. The system changes into the surroundings spontaneously
Answer» Correct Answer - C In a reversible process, the driving and the opposite forces are nearly equal, hence the system and the surroundings are nearly equal, hence the system and the surroundings always remain in equilibrium with each other.
