Gently pressing a balloon compresses the air inside, storing elastic potential energy. When the force is withdrawn, the stored energy allows the balloon to return to its original shape, demonstrating its capability to do work in the process.
How does gently pressing a balloon demonstrate its capability to regain its original shape?

Gently pressing a balloon demonstrates its capability to regain its original shape due to its elasticity. When pressure is applied, the rubber material of the balloon deforms temporarily. However, because of its elastic properties, the rubber molecules return to their original positions when the pressure is released, causing the balloon to regain its initial shape and size.
