Why is rusting of iron objects faster in the rainy season than in summer season?
Content of moisture in air is high in rainy season whereas air is almost dry in summer season.
Content of moisture in air is high in rainy season whereas air is almost dry in summer season. For rusting, the presence of both oxygen and water is essential. Rusting becomes faster, if the content of moisture in air is high. Hence, rusting of iron objects is faster in rainy season than in summer season.
