Question

Why are school bells made of metals?

Answer 1

Understanding the concept:

• Metals like copper, iron, etc are sonorous in nature.
• Sonority is a property of metals that produce a ringing sound on striking.

Explanation of school bells are made of metals:

• Metals are considered sonorous because they may make a ringing sound when struck by a solid object.
• Therefore school bells ( or in temples) are made up of metals.
• Since nonmetals like graphite is a non-metal, it is not sonorous.
