3. A piece of elastomer is 9 cm long. After hanging a weight from one end of the material, the length is measured to be 20 cm at room temperature (25 degrees C). a. What will be the length of the elastomer with the weight if the system is heated up to 125 C, (assume small strain is applicable)? b. Briefly explain if the material is behaving as an energetic or entropic elastic body.
