6. 2 In order for carbon dioxide gas to enter the air from dry ice, particles in the dry ice must: a. gain energy; b. boil; c. increase in pressure; d. undergo an exothermic change.

7. 2 a. gain energy.

8. 3 What occurs to a liquids particles, when a liquid becomes a gas?

9. 3 The particles break away from one another.

10. 4 How do the particles of water that evaporate from an open container differ from the particles that remain?

11. 4 The evaporated particles have more speed and higher energy.
