## Question

Define malleability as a property of materials.

## Short answer

Malleability is the ability to be hammered or rolled into thin sheets without cracking. It depends on plasticity under compression; gold, silver, lead, copper and aluminium are highly malleable, and heating usually increases it.

## Answer

**Malleability** is the property of a material by which it can be hammered or rolled into thin sheets without cracking or breaking. It depends on plasticity under compression. Gold, silver, lead, copper and aluminium are highly malleable, and heating usually increases malleability.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Malleability is the ability to be
   A. drawn into wires under tension
   B. stretched elastically
   C. hammered or rolled into thin sheets without cracking
   D. bent only when hot
   Answer: C. Drawing into wires is ductility. (Key point: Definition)

2. Highly malleable metals include
   A. cast iron and glass
   B. brick and stone
   C. concrete and cement
   D. gold, silver, lead, copper and aluminium
   Answer: D. These metals are highly malleable. (Key point: Examples)

3. Heating usually
   A. increases malleability
   B. decreases malleability
   C. makes it brittle always
   D. has no effect
   Answer: A. The answer says heating usually increases malleability. (Key point: Effect of heat)
