Question
Explain why rusting of iron objects is faster in coastal areas than in deserts.
Advertisements
Solution
- Both air and moisture are required for rusting to take place. In coastal areas, the quantity of moisture present in the air is greater than that in deserts.
- The amount of moisture in the air is even lower in desert areas. Therefore, iron objects rust faster in coastal areas than in deserts.
