Majuma Mganga period 7 Chemistry Rubber Bands and Spontaneity Purpose: The purpose of this activity was to determine if a chemical or a physical change is spontaneous. This activity was also designed to determine if a change is spontaneous by using change in enthalpy and change in entropy with the structure of polymers. Hypothesis: If you heat the rubber band and then streatch it‚ then the rubber band will become shorter meaning it will release eneregy because it is not relaxed and the
