Seth wanted to know how various metals reacted to weathering processes. He exposed three iron objects to the weather for 6 months. His data table is shown below. His teacher asks him later, "If the Law of Conservation of Mass is true, how did your samples gain more mass?" How should Seth best respond?

These materials reacted with unmeasured gases and compounds found in nature.
