Some gaseous oxygen from the air, reacts with the iron, forming rust (Fe + O2). This additional oxygen increases the total volume of, what was, just the nail.

Iron fillings have a much greater surface area and so are more exposed than a large iron nail which would have a smaller surface area exposed to oxygen and water.

Why is a bag of nails have more inertia than an equal sized bag of cotton?

Size generally refers to volume in respect to containers. As a result a bag filled with nails will have more mass than an equal sized bag filled with cotton. Inertia is proportional to mass and the velocity the mass is travelling at, or alternately the mass and the acceleration it is subjected to. As a consequence a bag filled with nails travelling at the same velocity (or subjected to the same acceleration) as an equal sized bag filled with cotton has a greater inertia due to its greater mass.
