Problem

Suppose you have a system made up of water only, with the container and everything beyond being the surroundings. Consider a process in which the water is first evaporated and then condensed back into its original container.

Is this two-step process necessarily reversible?

Solution

We are asked if this two-step process is necessarily reversible: Supposed you have a system made up of water only, with the container and everything beyond being the surroundings. Consider a process in which the water is first evaporated and then condensed back into its original container. 


reversible process is a specific way in which a system changes its state. 

In other words, we can restore the system to its original condition with no net change to either the system or its surroundings. 


An irreversible process is one that cannot simply be reversed to restore the system and its surroundings to their original states.
