Webrubber molecules in a crystal. When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat. This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat. WebThis will cause the polymers to stretch and the rubber band to lengthen. Next, if you take a hair dryer and heat the rubber band, the heat will cause the polymers to want to coil back up and you can watch the rubber band then shrink and pull the weight back up a little bit.

"WebA C=C bond is about 1.5 times as strong as a C=C bond. That would make it vibrate faster than a C-H bond. But µ (C-C) = 6, while µ (C-H) = 0.92. The reduced mass of a C-C pair is about 6.5 times that of a C-H pair. The greater reduced mass makes the C=C bond vibrate much more slowly than a C-H bond. " - Can bonds stretch when heated
