How to Expand a Rubber Band under Constant Tension

Can a rubber band expand under constant tension?

a) Yes

Explanation:

When you warm the rubber band under constant tension, it will expand instead of shrinking. This phenomenon occurs due to the increased vibrating motion of the rubber band's atoms as a result of the heat. The vibrating motion creates more space between the atoms, causing the rubber band to expand.

When a rubber band is stretched under constant tension, it has the intrinsic tendency to restore its original size and shape once the tension is released. Therefore, heating the rubber band while keeping it under constant tension will lead to expansion rather than shrinking.

This expansion is a result of the increased movement of the atoms within the rubber band structure, creating more space and causing the overall expansion of the band.

Understanding this principle can help you manipulate rubber bands effectively in various applications where controlled expansion is needed.
