Question

Why would iron filings rust faster than an iron nail?

Answer 1

Answer:

In explanation

Explanation:

Iron fillings rust faster than an iron nail due to the bigger surface area of iron fillings.

For a given mass of iron filings will have a much larger combined surface area than the same mass of nails.

Consider a x gm of iron fillings and x gm of iron nails then we will see that x gm of iron fillings will have greater surface area than x gm of iron nails. Since corrosion is a phenomenon that occurs primarily at the surface, so the larger the surface area, the higher will be the corrosion rate , assuming an equivalent mass of metal
