If the entropy of the system increase or decreases in the stretching of rubber band. Solution: The entropy of the system decreases in the stretching of rubber band. Explanation: The entropy of the system depends upon the randomness of molecules in the system. More randomly the molecules are placed in the system; more is the entropy of the system. The molecules of rubber band in unstretched state are placed randomly and no force is exerted on them. But when the rubber band is stretched, the molecules of rubber band exert pressure on them and they are placed in the order. Therefore, the entropy of the system decreases in the stretching of rubber. Conclusion: The entropy of the system decreases in the stretching of rubber band.
