FAQs on Malleability and Ductility-Physical Properties Video Lecture - Science (Curiosity) Class 7 - New NCERT

1. What is the difference between malleability and ductility?

Ans.Malleability is the ability of a material, usually metals, to be deformed or shaped into thin sheets without breaking, while ductility is the ability of a material to be stretched into a wire without breaking. Both properties are important for understanding how materials behave under stress.

2. Can you give examples of malleable and ductile materials?

Ans.Some common examples of malleable materials include gold, silver, and copper, which can be easily hammered into thin sheets. Ductile materials include copper and aluminum, which can be drawn into wires without snapping.

3. Why are metals generally more malleable and ductile than non-metals?

Ans.Metals have a unique atomic structure that allows their atoms to slide over each other when subjected to stress, which contributes to their malleability and ductility. Non-metals, on the other hand, usually have more rigid structures which make them brittle and less capable of deforming without breaking.

4. How does temperature affect the malleability and ductility of metals?

Ans.Increasing the temperature generally enhances the malleability and ductility of metals. When metals are heated, their atoms gain energy and can move more freely, allowing them to be shaped or drawn into wires more easily without breaking.

5. Why is it important to know about malleability and ductility in materials science?

Ans.Understanding malleability and ductility is crucial in materials science because it helps engineers and designers choose the right materials for specific applications, such as construction, electrical wiring, and manufacturing products that require specific shapes and strengths.
