Question

19.
1) Substances which break into smaller pieces or powdered when hammered are called brittle
II) Substances which can be spread into sheets when beaten are malleable
Choose the correct set suitable for the above respectively
A. Rock salt, glass
B. Gold, silver
C. Common salt, silver
D. Gold and zinc​

Answer 1

The option C that is common salt and silver, common salt is brittle and silver is malleable

Explanation:

1.Brittleness describes the property of a material that fractures when subjected to stress but has a little tendency to deform before rupture.

2.Brittle materials are characterized by little deformation, poor capacity to resist impact and vibration of load, high compressive strength, and low tensile strength.

3.Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A malleable fabric could be planate by blow or rolling.
