Lecture: Snapping a Rubber Band (15 minutes)

  • SWBQ: If you stretch and then let a rubber band snap, what will happen to the internal energy and the temperature of the rubber band?
  • This is an interesting example, as rubber bands may change temperature in either direction as it is being stretched, dependent on the type of rubber band used. However, because the process returns to its original state, you can use the First Law to show that the temperature must increase regardless.
