Section 2: Change of state – endothermic and exothermic changes
12. What does the term “change of state” mean?
13. What causes a change in state?
14. List the 5 changes of state we learned about.
15. When energy is taken in by a substance and changes state, it is called a
______________________________________ change.
16. Vaporization is the change of state from a liquid to a gas. This can occur in two ways.
What are the two ways?
17. Describe two ways that evaporation is different than boiling.
18. Why is sublimation unusual?
19. Explain how solid air fresheners are examples of sublimation.
20. When energy is lost by a substance and it changes state, it is called a
______________________________________ change
21. Fill in the table below.

22. Match the following circumstances with the change of state they describe:
a. Melting
d. sublimation
b. vaporization - boiling
c. condensation
e. freezing
f. vaporization - evaporation
