This might be a silly question, but what are examples of how you can do work on an open system?

Examples of open systems include a living plant, gasoline burning in an automobile engine, and boiling water without a lid. These systems are open systems because they freely allow energy and matter to be transferred in an out of the system.

In a more Laboratory-like setting, an open system could be a glass beaker into which you can place different substances. if you can also place it on some sort of heat source like a bunsen burner or cool it down in addition to the exchange of materials it will be an open system

The example I did in class with the reaction producing net 8 moles of gas in an open beaker.
