WebOct 4, 2024 · There are two ways that temperature affects the length of a stretched rubber band. The first is thermal expansion - an unstretched rubber band will, like most materials, tend to expand when heated. The second is a change to the Young's modulus - the proportion by which the rubber band will stretch when subject to a given stress or load. http://www.scienceline.ucsb.edu/getkey.php?key=4384
