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?

Yes

Explanation:

The possibility of evaporating and condensing is a proof of reversible reaction

No

Explanation:

No, because there is no evidence that the surroundings are also restored to their original state.

cannot be undone by exactly reversing the change to the system; Spontaneous processes are irreversible.
