उत्तर
Tiffin boxes are electroplated with tin but car bumpers are electroplated with chromium to protect them from rusting.
Explanation:
Tin is used for tiffin boxes because it is non-toxic and does not react with food acids, making it completely safe for storing meals. On the other hand, chromium is used for car bumpers because it provides a shiny, decorative finish while being highly resistant to scratches and weather wear. Both coatings effectively shield the underlying iron or steel from air and moisture, preventing rust.
