When most elastomeric polymers (e.g., a rubber band) are stretched, the molecules become more ordered, as illustrated here: Suppose you stretch a rubber band.

(a) Do you expect the entropy of the system to increase or decrease?

(b) If the rubber band were stretched isothermally, would heat need to be absorbed or emitted to maintain constant temperature?

(c) Try this experiment: Stretch a rubber band and wait a moment. Then place the stretched rubber band on your upper lip, and let it return suddenly to its unstretched state (remember to keep holding on). What do you observe? Are your observations consistent with your answer to part (b)?
