Questions and Answers

What is the result when energy is transferred to a substance?

  • The atoms/molecules do not change speed.
  • The atoms/molecules lose energy and move slower.
  • The atoms/molecules expand and their volume decreases.
  • The atoms/molecules gain energy and move faster. (correct)
  • What happens to the volume of a substance when it is warmed?

  • The volume remains the same as the atoms/molecules do not change size.
  • The volume changes randomly and unpredictably.
  • The volume increases as the atoms/molecules spread further apart. (correct)
  • The volume decreases as the atoms/molecules get closer together.
  • What is the relationship between temperature and the speed of atoms/molecules?

  • The faster the atoms/molecules move, the higher the temperature. (correct)
  • Temperature is a measure of the total energy of the atoms/molecules.
  • The faster the atoms/molecules move, the lower the temperature.
  • Temperature and speed of atoms/molecules are unrelated.
