प्रश्न
What will happen if....? And why?
A bell is made of wood.
उत्तर
If a bell is made of wood, it will not ring. The bells are made up of metals like copper etc. as they show the property of sonority i.e. the ability to produce a ringing sound when struck upon. Wood does not have this property and hence cannot be used to make bells.
