Question
Examples of corrosion are
- Spoilage of food
- Tarnish on silver
- Melting of ice
- Wearing and tearing of moving machine parts.
Hint:
Tarnish of silver is the formation of oxide coating over silver.
The correct answer is: Tarnish on silver
- Corrosion is a natural process that transforms a refined metal into a more chemically stable form like oxide, hydroxide or sulphide.
- Tarnish of silver is the formation of oxide coating over silver.
- Spoilage of food is called rancidity.
