Question

Pick out the material which cannot be damaged by the process of corrosion.

• A. Vehicles
• B. Iron nails
• C. Bridges
• D. Plastic bags

Answer 1

The correct option is D Plastic bags

Corrosion is a chemical reaction that happens in metals when they are exposed to certain external factors. Non-metals don't undergo corrosion. Vehicles, Iron nails, and bridges are made of different metals that can eventually corrode. Plastic bags on the other hand are made from plastic only, which is not a metal and it does not corrode.
