(a)
To determine: 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.
(b)
To determine: If the heat is absorbed or emits to maintain constant temperature in the stretching of rubber.
(c)
To determine: The observation of the given experiment.

The monomers, ethylene glycol and terepthalic acid, are given. Add bonds and remove atoms as necessary to show the structure of a two repeat unit portion of a longer polymer chain of PET. You may need to zoom out to see the complete structure of all four monomer units.
