What happens when a rubber band is stretched ? (2024)

Hint:The elasticity of a rubber band is affected in an odd way by temperature. The rubber band contracts when heated and expands when cooled. When you stretch a rubber band, it releases heat, but when you release it after it has been extended, it absorbs heat, making the surroundings a little colder. This is due to the unstressed state's higher entropy, which is more intertwined and thus has more states open. The ability to transform thermal energy into work as the rubber relaxes is allowed by the relaxed state's higher entropy.

Complete answer:
In nature, a rubber band is an elastic substance. It changes shape when extended and returns to its original shape when the applied force is withdrawn. That is why, after being a solid, a rubber band changes shape. Furthermore, if too much stress is applied, the rubber band will snap.

When an external force is applied to a solid body, the weight, volume, or form of the body changes. The body begins to revert to its original form and scale as external pressures are withdrawn. Elasticity is a feature of a body that allows it to return to its original form (or size) after external forces have been withdrawn.

When a rubber band is extended, the force that acts on it is called the elastic force. Elasticity is described as the ability of a substance to stretch and return to its original shape after being stretched. As an object is bent, it exerts an opposing force, which is known as elastic force.
