Yes a physical property "Elasticity" is the cause for such a stretching
That is called Hooke's Law. When a force F is applied to an object it will stretch X in proportion to its spring constant K according to F =KX
Yes - it's still a rubber band.
Yes - it's still a rubber band.
You can give the rubber band potential energy by stretching the rubber band, however if you let it go and it moves then it will no longer be potential energy.
Yes
It has potential to do work. Looking at it another way, it requires energy to stretch the rubber band; this energy can be recovered - for example, by pulling something - when the rubber band gets back to its normal position.
Stretching a rubber band is a physical change.
Yes - it's still a rubber band.

Rubber is elastic. After streching is stopped, it will regain its shape.
Elastic potential energy.
Yes
It has potential to do work. Looking at it another way, it requires energy to stretch the rubber band; this energy can be recovered - for example, by pulling something - when the rubber band gets back to its normal position.
Stretching the rubber band would lengthen it. It is the sentence containing the lengthen word.
No. The rubber band stores energy as elastic potential energy. U = (1/2)*k*(L)^2 where, U is the stored energy k is the spring constant for the rubber band L is the displacement
Well, if you extend a rubber band, after a while tension begins to build up and the rubber band wants to retract (return to its original shape), same principle with a bungee jump, the band is extended to it's limit and wants to return.
