I did an experiment where i placed a rubber band in water at different temperatures (-15celcious till 90celcious15°C till 90 °C) , and then a put a constant mass on the rubber band, to see how far it would stretch. What i noticed was that at higher temperatures (90 degrees) it would stretch further then at colder temperatures. I dont really understand why the increase in temperature allows for the rubber band to stretch more. because doesnt entropy dictate that at lower temperatures their is lower entropy and thus it should stretch more. Furthermore i compared my reserch to other studies but none provide an explation to what causes rubber to stretch more when a constant force is applied at higher temperatures? I would also like to mention that rubber bands do not follow thermal expansion so thus at warmer temperatures the moleculues become more tangled and contract,whilst at colder temperatures the rubber expands.
