elasticity
When force is applied to rubber, the elastic tension energy disrupts bonds, and changes the structure, as if heat is applied. Heat is actually absorbed by the rubber, as its elasticity increases, while undergoing the "stretch" deformation. When force is no longer applied, the streched rubber collapses, releasing heat, as the structure reverses form, to its starting molecular conformation.
Stretching a rubber band is a physical change.
Stretching of a rubber band is a physical change because the molecular structure of the rubber remains the same even after it is stretched. No new substances are formed during stretching, and the rubber band can return to its original shape and properties once the force is removed.
This depends on the size of the rubber band, the materials and impurities in the rubber band, and the speed at which you stretch it, as well as the conditions that the rubber band has been under.
Yes - it's still a rubber band.
Stretching a rubber band is a physical change because it alters the shape and size of the rubber band without changing its chemical composition. The rubber band can return to its original state by releasing the tension, demonstrating that no new substances were formed during the stretching process.
One example of stretching a rubber band is pulling it from both ends to increase its length and storing potential energy in the process.
Rubber is elastic. After streching is stopped, it will regain its shape.

Elastic potential energy.
If the stretching of a rubber band is too much, it can lead to the band losing its elasticity and eventually breaking. This is because the molecular structure of the rubber band becomes permanently deformed, affecting its ability to return to its original shape.
