Questions and Answers

Which of the following statements accurately describes the relationship between molecular motion and temperature?

  • Faster molecular motion corresponds to higher temperatures. (correct)
  • Molecular motion and temperature are independent properties.
  • Molecular motion and temperature are inversely proportional.
  • Slower molecular motion corresponds to higher temperatures.

    • When a substance is heated, what happens to the volume of the substance?

  • The volume may increase or decrease depending on the substance.
  • The volume decreases as the atoms/molecules move closer together.
  • The volume increases as the atoms/molecules move farther apart. (correct)
  • The volume remains constant as the atoms/molecules do not change size.

    • If the atoms/molecules of a substance are observed to be moving slower, what can be inferred about the temperature of the substance?

  • The temperature of the substance is remaining constant.
  • The temperature of the substance is decreasing. (correct)
  • The temperature of the substance is increasing.
  • The temperature of the substance cannot be determined.

    • Which of the following statements accurately describes the behavior of atoms/molecules when a substance is cooled?
