Can bonds stretch when heated

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. http://scienceline.ucsb.edu/getkey.php?key=3440
