Question

Brittleness is a property of solid which:
A.They break in to small piece
B.The solid does not back to its original shape
C.Solid regains its original shape
D.None of these

Answer 1

We must have to know that a metal has several physical and chemical properties. And brittleness is one of the physical properties of metal. And others are malleability, ductility, etc. and the metals have high melting points, shiny, and they are good conductors of electricity and heat. But the nonmetal materials do not have any properties. Which are poor conductors of electricity and heat and have very low melting points.

Complete answer:
We also remember that the brittleness is the property of solid which they break into small pieces. If we apply stress into a material, it will be brittle and there is a formation of small pieces. But there is no significant deformation. And it represents poor capacity to resist impact, and its compressive strength is very high, but the tensile strength will be less.
Therefore, the brittleness is the property of solid which they break into small pieces. Hence, option (A) is correct.
If the material has the property to reform to its original state is known as elasticity. And the solid does not return to its original shape and it’s not due to its brittleness property. Hence, the option (B) is incorrect.
The solid regains to its original state not due to the property of brittleness. Hence, option (C) is incorrect.
If the material can break into small pieces, that type of property is known as brittleness. Hence, the option (D) is incorrect.

Note:
We have to know that solid materials have different properties like, it can break into small pieces, and it does not return to its original shape etc. And if the solid can break into small pieces, that type of property is known as brittleness. And it is represented by deformation, tensile strength, compressive strength etc. its tensile strength is always very low.
