Step 1: Understand what a reversible process is. It is a process that can be reversed without leaving any change in the system or surroundings.
Step 2: Learn about quasi-static processes. A quasi-static process is one that happens very slowly, allowing the system to stay in equilibrium at all times.
Step 3: Realize that for a process to be reversible, it must be quasi-static. This means it should happen so slowly that the system can adjust and remain balanced.
Step 4: Remember that if a process happens too quickly, it creates irreversibilities, making it impossible to reverse.
Reversible Process – A process that can be reversed without leaving any change in the system and surroundings.
Quasi-static Process – A process that occurs infinitely slowly, allowing the system to remain in equilibrium at all times.
