Question

Bells in school and temples are made of metals because_________.

• A. metals are hard
• B. metals are ductile
• C. metals are malleable
• D. metals are sonorous

Answer 1

The correct option is D

metals are sonorous

• Metals are the ones that are electropositive in nature and have the tendency to lose electrons and form cations (positively charged species).
• Sonorous is the property of any substance to generate sound when hit with any other hard solid.
• Since metals are sonorous in nature, they can be utilized in the manufacturing of bells to generate sound.

• Metals are firm and rigid in nature but its hard nature can not be utilized to produce sound.
• Ductility is the property of converting a metal into thin wires by hammering without breaking.
• Since the property of ductility is not associated with the production of sound in bells, the given option is incorrect.
• Malleability is the property of converting a metal into thin sheets by hammering without breaking.
• Since the property of malleability is not associated with the production of sound in bells, the given option is incorrect.

Hence, option D is correct. Metals are sonorous and therefore, bells in school and temples.
