Question

What do you understand by corrosion? Give two measures for protection against it.

Hint:

Corrosion can be minimized by using protective coatings or choosing corrosion-resistant materials.

Answer 1

Corrosion is the process by which metals deteriorate due to chemical reactions with their environment, typically with oxygen or moisture. For example, iron reacts with water and oxygen to form rust (iron oxide).
Two measures for protection against corrosion are:
1. Galvanization: Coating the metal with a layer of zinc to protect it from environmental factors.
2. Use of corrosion-resistant materials: Choosing alloys like stainless steel, which do not easily corrode.
