Questions and Answers

What happens when a substance is heated?

  • The atoms/molecules contract, decreasing the volume of the substance.
  • Energy is transferred to the substance, causing the atoms/molecules to move faster. (correct)
  • Energy is transferred from the substance, causing the atoms/molecules to move slower.
  • The atoms/molecules expand, increasing the volume of the substance.

When the atoms/molecules in a substance move faster, what happens to the temperature?

  • The temperature increases. (correct)
  • The temperature fluctuates randomly.
  • The temperature decreases.
  • The temperature remains the same.

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

  • The volume decreases due to the atoms/molecules contracting. (correct)
  • The volume remains the same.
  • The volume fluctuates randomly.
  • The volume increases due to the atoms/molecules expanding.
