Malleability and Ductility-Physical Properties
Summary
TLDRThis video from moomoomath and science explores the physical properties of malleability and ductility. Malleability allows solids like gold, silver, and copper to be hammered into various shapes without breaking, while ductility enables materials to be drawn into thin sheets or wires. The video illustrates these concepts with examples, including the use of malleable gold for crafting a piggy bank and ductile copper for making wires, emphasizing the practical applications of these properties in everyday life.
Takeaways
- 🔨 Malleability is the property of a solid material to be hammered or rolled into different shapes without breaking.
- 📏 Malleable materials can be flattened into thin sheets, such as gold, silver, and copper.
- 🛠 Metals are generally malleable, which has allowed blacksmiths to create useful objects by hammering them.
- 🐷 An example of malleability is the creation of a piggy bank from gold, showcasing gold's malleability.
- 🧵 Ductility is the ability of a material to be drawn into a thin wire without breaking.
- 🔌 Ductility is important in creating wires, with copper being a common material used for this purpose.
- 🌟 Gold is also ductile and can be fashioned into wires, highlighting its versatility in applications.
- 💎 Not all materials are ductile; glass, for instance, is not very ductile and cannot be easily drawn into wires.
- 📚 The video discusses two physical properties: malleability and ductility, which are important for material applications.
- 📈 The script provides examples of materials that are both malleable and ductile, emphasizing their industrial uses.
- 🎥 The video is part of a series by moomoomath, which uploads new math and science content daily.
Q & A
What are the two physical properties discussed in the video?
-The two physical properties discussed in the video are malleability and ductility.
What is malleability in the context of materials?
-Malleability is the ability of a solid material to be hammered or rolled into thin sheets without breaking.
Can you provide examples of malleable metals mentioned in the video?
-The video mentions gold, silver, and copper as examples of malleable metals.
How is malleability demonstrated in the video with a piggy bank?
-The video demonstrates malleability by showing that gold, being malleable, can be fashioned into a piggy bank.
What is ductility and how does it differ from malleability?
-Ductility is the ability of a material to be stretched into wire without breaking, which is similar to malleability but specifically refers to the ability to form into wire.
Which metals are mentioned as examples of ductile materials in the video?
-The video provides gold, copper, and silver as examples of ductile materials.
Why is copper used to make wires according to the video?
-Copper is used to make wires because it is ductile, allowing it to be drawn into thin wires without breaking.
Can glass be considered ductile based on the information in the video?
-No, the video states that glass is not very ductile.
What is the practical application of malleability and ductility in the video's example of a piggy bank?
-The practical application is that malleability allows gold to be shaped into a piggy bank, showcasing its ability to be hammered into various forms without breaking.
What does the video suggest about the value of a piggy bank made from malleable gold?
-The video suggests that while the piggy bank itself may not be valuable, the malleability of gold is valuable as it allows for its creation.
How does the video conclude the discussion on malleability and ductility?
-The video concludes by summarizing the physical properties of malleability and ductility and encouraging viewers to subscribe and share for more math and science videos.
Outlines
🔨 Malleability and Ductility in Materials
This paragraph introduces two physical properties of materials: malleability and ductility. Malleability is the ability of a solid to be bent or hammered into various shapes without breaking, allowing materials like gold, aluminum, copper, and silver to be flattened into thin sheets. Ductility, on the other hand, is the property that enables a material to be drawn into a thin wire without breaking, which is exemplified by metals such as gold and copper. The paragraph also mentions the crafting of a piggy bank from malleable gold and the use of copper for making wires, highlighting the practical applications of these properties in everyday life.

Transcripts
welcome to moomoomath and science in
this video I'd like to talk about two
physical properties now the ability and
ductility malleability is the ability of
a solid to bend or be hammered into
other shapes without breaking
if malleable a material can be flattened
into thin sheets by hammering or rolling
examples of malleable medals are gold
i'm aluminum copper silver because
metals of metals are malleable
blacksmith have been able to hammer
metals into helpful objects over the
years prepare a malleable metal to this
piggy bank which is not valuable because
gold is malleable it can be fashioned
into jory ductility is a physical
property of a material with the ability
to be hammered into thin sheets or
stretched into wire without breaking a
ductile substance can be drawn into a
wire again most metals of good examples
of ductile materials including gold
copper and silver aluminium is not very
ductile copper is used to make wires and
gold can also be used to make wire this
glass is not very ductile
so there we go to physical properties
malleability and ductility thanks for
watching and moomoomath uploads a new
math and science video every day please
