Questions and Answers

What happens when a substance is heated?

  • Energy is transferred from the substance and its temperature decreases
  • The atoms/molecules gain energy and move faster, resulting in stronger and more frequent collisions (correct)
  • The atoms/molecules move slower and the volume of the substance decreases
  • The atoms/molecules themselves expand in size
  • What is the relationship between temperature and the speed of atoms/molecules?

  • Temperature is only related to the volume of the substance
  • Temperature is not related to the speed of atoms/molecules
  • Temperature is directly proportional to the speed of atoms/molecules (correct)
  • Temperature is inversely proportional to the speed of atoms/molecules
  • What happens to the volume of a substance when it is cooled?

  • The volume increases as the atoms/molecules move faster
  • The volume remains the same as the atoms/molecules do not change in size
  • The volume decreases as the atoms/molecules get closer together (correct)
  • The volume changes randomly and is not related to cooling
