Questions and Answers

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

  • The atoms/molecules shrink 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 do not change position and the volume remains the same
  • What is the relationship between temperature and the speed of particles?

  • Higher temperature corresponds to slower particle movement
  • Temperature is unrelated to particle speed
  • Temperature does not affect particle speed
  • Lower temperature corresponds to faster particle movement (correct)
  • How does cooling a substance affect the energy of its atoms/molecules?

  • The atoms/molecules gain energy and move faster
  • The energy of atoms/molecules remains constant during cooling
  • The atoms/molecules lose energy and move slower (correct)
  • Cooling has no impact on the energy of atoms/molecules
