The ability of a substance to be shaped or drawn into a wire……..
a) ductility
b) malleability
c) conductivity
d) solubility
Explanation:Ductility is a mechanical property commonly described as a material's
amenability to drawing. In materials science, ductility is defined by the
degree to which a material can sustain plastic deformation under tensile stress
before failure. Ductility is an important consideration in engineering and manufacturing.
Which
of the following substance/s is/are ductile?
a) copper
b)
silver
c) gold
d) all of these
The ability of a substance to be hammered in a sheet……..
a) ductility
b) malleability
c) conductivity
d) solubility
Explanation: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.
Which
of the following substance/s is/are malleable?
a) copper
b)
silver
c) gold
d) all of these
Which of the following metal is most malleable?
a) copper
b) silver
c) gold
d) all of these
The temperature at which solid changes into liquid is called…….
a) boiling point
b) melting point
c) freezing point
d) transition temperature
