Verified Answer
Which of the following is true about the hardness of materials?a)Rubbe...
- Rubber is a flexible and elastic material, making it softer than iron, which is a hard and rigid metal.
- Sponge, though it can be very soft and compressible, is generally softer than both rubber and iron.
- Iron is the hardest among these materials, known for its strength and rigidity.
- Therefore, the correct statement is A: Rubber is harder than sponge but softer than iron.
- Sponge, though it can be very soft and compressible, is generally softer than both rubber and iron.
- Iron is the hardest among these materials, known for its strength and rigidity.
- Therefore, the correct statement is A: Rubber is harder than sponge but softer than iron.

Understanding Material Hardness
Material hardness refers to the resistance of a material to deformation, scratching, or penetration. Different materials have varying levels of hardness based on their composition and structure.
Comparison of Materials
- Rubber:
- Rubber is generally flexible and can be easily deformed.
- It has a moderate hardness; it is softer than many metals but can be harder than some softer materials.
- Sponge:
- Sponge is a soft, porous material that compresses easily.
- It is much softer than rubber and thus has a lower hardness.
- Iron:
- Iron is a metal known for its strength and hardness.
- It is significantly harder than both rubber and sponge.
Analysis of the Options
- Option A: "Rubber is harder than sponge but softer than iron."
- This statement is true. Rubber indeed has a higher hardness compared to sponge, which compresses easily. However, rubber is softer than iron, a hard metal.
- Option B: "Sponge is harder than rubber but softer than iron."
- This is false because sponge is softer than rubber.
- Option C: "Iron is softer than rubber but harder than sponge."
- This is incorrect since iron is not softer than rubber.
- Option D: "Rubber is softer than both sponge and iron."
- This is false because rubber is harder than sponge.
Conclusion
The correct answer is option A because it accurately represents the relative hardness of rubber, sponge, and iron, confirming that rubber is indeed harder than sponge but softer than iron.
