Exam points

  • Relate absolute temperature in kelvin to average particle kinetic energy and use KE or velocity relationships to predict factor changes.
  • Explain how heating changes particle motion, collision frequency and gas volume, and interpret gas-state physical properties such as atomic volume using particle-model reasoning.
