A rubber band changes it's shape on stretching. Why do we call it a solid? Give reason.?

Question

Answer

Yes SONI... its true sis... but the rubber changes its shape only when external force is applied. It does not changes its shape on its own. We need to apply some force. It has its own rigidity... THANKS FOR UPLOADING SUCH A GOOD QUES. TO IMPROVE OUR KNOWLEDGE.... HOPE MY ANSWER HELPS U.. BEST WISHEZ SIS

Answer

Because the rubber band can not maintain its shape and very less force applied on it can change its shape

Answer

Introduction:
A rubber band is commonly classified as a solid material despite its ability to change shape when stretched. This classification is based on various scientific principles and characteristics that define solids. In order to understand why a rubber band is referred to as a solid, we need to explore the properties and behavior of solids.

Definition of a Solid:
A solid is one of the three fundamental states of matter, along with liquids and gases. It is characterized by having a definite shape and volume, as well as strong intermolecular forces that hold its constituent particles together in a fixed arrangement.

Key Points:
1. Definite Shape: Solids maintain a fixed shape and do not flow like liquids or gases. This is because the particles in a solid are tightly packed and have limited freedom of movement.

2. Strong Intermolecular Forces: Solids possess strong intermolecular forces, such as ionic, covalent, or metallic bonds, which hold their particles together. These forces are responsible for the rigid structure and stability of solids.

3. Elasticity: Solids exhibit elasticity, which refers to their ability to deform under the influence of an external force and return to their original shape when the force is removed. This property is also observed in rubber bands.

4. Deformation: When a rubber band is stretched, it undergoes a temporary change in shape. This change occurs due to the stretching of the polymer chains present in the rubber, allowing them to slide past each other. However, once the stretching force is released, the intermolecular forces cause the rubber band to revert to its original shape.

5. Molecular Structure: The molecular structure of rubber bands consists of long polymer chains, which are interconnected by weak intermolecular forces. These chains can slide and reposition themselves when stretched, contributing to the rubber band's elasticity.

Conclusion:
Despite its ability to change shape when stretched, a rubber band is classified as a solid material. This classification is based on the solid's overall behavior and characteristics, including its definite shape, strong intermolecular forces, and the ability to return to its original shape after deformation. While a rubber band may exhibit temporary changes in shape, its fundamental properties align with those of solids.
