Entropy can only be decreased in a system if?

If external work is done on the system

Explanation:

The 2nd law of thermodynamics states that entropy of an isolated system can never decrease over time. An isolated system is defined as a system which does not exchange energy or matter with the surrounding (an example of isolated system is a closed box made of insulating material, which cannot exchange neither matter nor heat with the environment). In such a system, entropy can never decrease.

However, if the system is not isolated, its entropy can be decreased. In fact, if the system is not isolated, we can do external work and decrease its internal entropy.
