    Rubber which is an elastomer behaves somewhat like an ideal monoatomic gas,
    inasmuch as (to good approximation) elastic polymers do not store any potential energy in stretched chemical bonds or elastic work done in stretching molecules,
    when work is done upon them. Instead, all work done on the rubber is "released" (not stored) and appears immediately in the polymer as thermal energy.
    see for details https://en.wikipedia.org/wiki/Rubber_elasticity
