This activity demonstrates the physical property of malleability in metals. We will try to change the shape of the metal pieces.
Malleability of Metals Activity
Aim of the activity
To study the malleability of metals like iron, zinc, lead, and copper
Materials Required
1. Metal pieces
(iron, zinc, lead & copper)
2. Hammer
Procedure
We
place a piece of iron on a hard surface and strike it 4 to 5 times with a hammer.
After that, we observe and record the change in shape.
Now
we repeat this with other metal sample pieces.
Observation
Metal
|
After
hammering |
Iron
|
Hard
to deform, slight change in shape |
Zinc
|
Become
flat, but cracks appear |
Lead
|
Easily
flattens and deforms |
Copper
|
Spread
like thin sheet |
Explanation
When
we beat metals with a hammer, they turn into sheets; this property of metals is known
as “ malleability”.
Copper
and lead show high malleability, and iron is hard to change its shape.
Conclusion
This
activity explains that metals can be beaten into sheets. This is a physical property
of metals.
What is malleability?
Metals
can be beaten, pressed into sheets/foils; this property of metals is called
malleability.
Frequently Asked Questions
1. Do all
metals have equal malleability?
Answer
– No, some metals are more malleable than others.
2. What is
the use of malleability of metals in daily life?
Answer
– Due to this property of metals, foils, utensils, sheets, pipes, coins are
made.
3. What name
is given to the material which show malleability?
Answer
– Malleable metals
