Questions and Answers

What happens when a substance is heated?

  • The atoms/molecules gain energy and move faster, leading to stronger and more frequent collisions. (correct)
  • The atoms/molecules stay the same speed, but the volume of the substance increases.
  • The atoms/molecules lose energy and move slower, leading to weaker and less frequent collisions.
  • The atoms/molecules expand in size, causing the volume of the substance to increase.

What is the relationship between temperature and the speed of atoms/molecules?

  • The slower the atoms/molecules move, the higher the temperature.
  • Temperature has no relationship to the speed of atoms/molecules.
  • Temperature is a measurement of the average speed of atoms/molecules. (correct)
  • The faster the atoms/molecules move, the lower the temperature.

What happens when a substance is cooled?

  • The atoms/molecules shrink in size, causing the volume of the substance to decrease.
  • The atoms/molecules stay the same speed, but the volume of the substance decreases.
  • The atoms/molecules lose energy and move slower, leading to weaker and less frequent collisions. (correct)
  • The atoms/molecules gain energy and move faster, leading to stronger and more frequent collisions.
