Rubber band is a solid material made from natural or synthetic rubber. It is considered a solid because it has a definite shape and volume, and its molecules are tightly packed together. However, rubber band is a special type of solid that can undergo deformation under certain conditions.

Elasticity of Rubber Band

Rubber band is an elastic material, which means it can be stretched and then return to its original shape and size when the force is removed. This property is due to the arrangement of long polymer chains that make up the rubber material. When the rubber band is stretched, the polymer chains straighten out and align in the direction of the force. When the force is removed, the chains recoil and return to their original state, causing the rubber band to regain its original shape.

Deformation of Rubber Band

While rubber band can return to its original shape after being stretched, it can also be deformed permanently under certain conditions. For example, if a rubber band is stretched beyond its limit, it may break or lose its elasticity. Similarly, exposure to high temperatures or chemicals can cause the rubber band to deteriorate and lose its shape. In these cases, the rubber band is no longer able to return to its original shape and is considered deformed.

Conclusion

In summary, rubber band is a solid material with the ability to deform under certain conditions. Its elasticity is a unique property that allows it to stretch and return to its original shape, while deformation can occur when the material is stretched beyond its limit or exposed to unfavorable conditions.

Rubber band changes its shape under force and when the force is removed it regains it's shape. But if excessive force is applied it may break. solids can break but it is difficult to change their shape, so it is rigid.
