8*(15). Molecular structure of rubber involves long cross-linked polymer chains. When expanded, the chains become extended and their entropy becomes smaller (a fully stretched molecular chain obviously has fewer possible conformations as compared to a randomly coiled chain). Based on this fact, explain, mathematically, why rubber tends to contract when heated, unlike most other materials.
