Question

Define ductility ,malleability, sonorous

Answer 1

1. The ability of metals to be drawn into thin wires is called ductility.

2. The ability of some metals to be beaten into thin sheets is called malleability.

3. The ability to produce a sound on striking a hard substance is called sonority.

Answer 2

hey mate ....

EID MUBARAK :)

here is your answer:

. Lustrous => It is the property of many metals (exception, Diamond, a non metal) which makes them shine by reflecting the light falling on their surface, when it is polished, e.g., iron rods, gold, silver.

. Malleability => It is the property of any solid and hard metal (and/or non metal) which makes them deformed under pressure. It helps to make thin sheets of metals, e.g., tin cans, foils, etc.

The materials are called “malleable materials”.

. Ductility => It is the ability of solid and hard metals (and/or non metals) which can be stretched under tensile strength, e.g., thin wires, etc.

The property are called “ductile materials”.

Any material with high malleability can be highly ductile.

hope it helps...

please mark as the brainliest if it helped you :)
