Question

Name the property (a) which allows metals to be hammered into thin sheets.
(b) which enables metals to be drawn into wires.

Answer 1

a)Malleability

b)Ductility

Explanation:

• Different substances have diferent properties. Some substances have the property of being drawn into a sheet, and others have the property of being drawn into a wire.
• Malleability of a product is a property by which a substance can be beat into to make new products like a sheet or plane surface.
• This type of change usually happens because of the normal stress.
• Ductility of a product is a property of a substance which helps it get drawn into a wire.
• This type of property is caused by the shear forces applied.
• These forces act along the layers of  the object and helps it slide on the layers.
• Hence property a) is mallebaility and property b) is ductility.

Answer 2

Ductility for Wires & Malleability for Sheets

Explanation:

• a.) The Property of Metals (Physical) which makes them be hammered, rolled or pressed without breaking into thin sheets is called Malleability.  

Or

The Property owing to which the metal gets deformed into a new shape under compression.

• b.) The Property of a material to go through plastic deformation (Before Rupture) is called Ductility. It can be expressed in terms of percent area deduction or percent elongation from test. (Tensile)
