Questions and Answers

What happens when a substance is heated?

  • The atoms/molecules spread further apart and the volume decreases
  • The atoms/molecules gain energy and move faster (correct)
  • The atoms/molecules get closer together and the volume increases
  • The atoms/molecules lose energy and move slower

    • What is temperature a measurement of?

  • The average speed of the atoms/molecules (correct)
  • The volume of the substance
  • The mass of the atoms/molecules
  • The number of atoms/molecules

    • What happens when a substance is cooled?

  • The atoms/molecules get closer together and the volume decreases
  • The atoms/molecules gain energy and move faster
  • The atoms/molecules lose energy and move slower (correct)
  • The atoms/molecules spread further apart and the volume increases
