  11. Quick Quiz Question 1 • Telescope • b. Stethoscope • c. Microscope • d. Thermometer • Which of these forms of technology measure molecular motion of substances?

  12. Quick Quiz Question 2 • The particles get closer together as the gas expands. • b. The molecules bond together so they take up less space. • The size of the molecules is reduced as the gas contracts. • d. The particles get closer together as the gas contracts. • Why does the volume of a gas decrease if heat energy is removed?

The winter cold will make the rails contract. • Why do engineers design and build railroad tracks with a gap between the metal rails?

  14. Quick Quiz Question 4 • The metal particles melt in the hot water. • b. The metal particles move closer together in the hot water. • The metal particles move apart in the hot water. • d. The particles do not move, but the water lubricated the lid. • Why does hot water make it easier to remove a lid on a jar?
