Correct Answer - Option 1 : Malleability
Explanation:
Malleability:
Malleability is the property by virtue of which a material may be hammered or rolled into thin sheets without rupture. This property generally increases with the increase of temperature.
Malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to compressive force.
Lead, soft steel, wrought iron, copper and aluminium are some materials in order of diminishing malleability.
Ductility:
Ductility is the property of the material that enables it to be drawn out or elongated to an appreciable extent before rupture occurs.
The percentage elongation or percentage reduction in the area before rupture of a test specimen is the measure of ductility. Normally if percentage elongation exceeds 15% the material is ductile and if it is less than 5% the material is brittle.
Lead, copper, aluminium, mild steel are typical ductile materials.
Plasticity:
This is the ability of a material to deform without any rupture by a non-returnable way. After removing the load there are staying permanent deformations.
