Understanding Sponge Compression
When a sponge is compressed, it undergoes a physical change due to its structure and the air trapped within it. Let's explore the details:
Structure of a Sponge
- A sponge is made up of a network of flexible fibers that create numerous tiny pores.
- These pores are filled with air, giving the sponge its buoyancy and compressibility.
What Happens During Compression?
- Expulsion of Air: When you squeeze a sponge, you apply pressure that forces the air trapped in its pores out.
- Reduction in Volume: As the air is expelled, the sponge's overall volume decreases, leading to a temporary reduction in size.
- Return to Original Shape: Once the pressure is released, the sponge can absorb water and expand back to its original size due to its elastic properties.
Why Other Options Are Incorrect
- Option A (Stays the Same Size): This is incorrect because the sponge visibly changes size when compressed.
- Option C (Becomes Solid): A sponge remains a porous material even when compressed; it does not turn solid.
- Option D (Dissolves): Compression does not cause a sponge to dissolve; it only expels air.
Conclusion
In summary, the correct answer is option 'B' because the process of compressing a sponge primarily results in the expulsion of the air trapped within it, allowing it to change size temporarily. Understanding this behavior is essential in both practical applications and scientific studies of materials.

When a sponge is compressed, the following occurs:
- The air trapped inside the sponge is forced out.
- This action reduces the sponge's volume.
- As a result, the sponge becomes denser and easier to handle.
In summary, compressing a sponge expels air, allowing it to be compacted.
