With respect to Part A of the lab, how can the signs of ΔH and ΔS for rubber stretching and relaxation be interpreted based on changes in chemical bonds or intermolecular forces? Based on your observations what happens to the strength/ number of the intermolecular attractions between neighboring rubber molecules when the balloon is stretched? Based on what you know about the chemical structure of rubber, are the signs for ΔS spontaneous and ΔS nonspontaneous consistent with what is happening to the rubber during the spontaneous and non-spontaneous processes?
