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?

Hello everyone. So in this video, we're given this picture right over here, that kind of represents our elastic american polymers such as rubber bands and becomes more organized when they're stretched out. So here it's before stretched out. This is after stretched out. We see that this is more organized. So the question is that if we have a rubber band or rubber tubing and it's being stretched out, what the entropy of the system increase or decrease. So when a rubber band is stretched out, the system is going to be more ordered and therefore are less.
