Questions and Answers

What happens to the volume of a substance when it is warmed?

  • The atoms/molecules remain the same distance apart and the volume decreases
  • The atoms/molecules get closer together and the volume decreases
  • The atoms/molecules spread further apart and the volume increases (correct)
  • The atoms/molecules move closer together and the volume increases

    • Which statement is true about the relationship between temperature and atom/molecule speed?

  • Lower temperature means no change in atom/molecule speed
  • Lower temperature means faster atom/molecule speed
  • Higher temperature means faster atom/molecule speed (correct)
  • Higher temperature means slower atom/molecule speed

    • What happens to the collisions between atoms/molecules when a substance is cooled?

  • Collisions become negligible
  • Collisions are weaker and less frequent (correct)
  • Collisions are stronger and more frequent
  • Collisions remain the same strength but occur less frequently
