Questions and Answers

What happens when energy is transferred to a substance?

  • The temperature decreases and the volume increases
  • The atoms/molecules themselves expand
  • The atoms/molecules lose energy and move slower
  • The atoms/molecules gain energy and move faster (correct)

Which of the following statements is true about cooling a substance?

  • The atoms/molecules expand and the volume increases
  • The collisions between atoms/molecules become stronger
  • The temperature increases due to slower atomic motion
