Understand the Problem
The question is asking for the completion of statements regarding changes of state in matter and vocabulary matching related to those concepts.
Answer
1. evaporation 2. freezing 3. freezing 4. decreases 5. condensation
- Both sublimation and evaporation occur only on the surface of a substance. 2. The reverse of melting is freezing. 3. When butter is heated it melts, and when that melted butter cools and solidifies, the process is called freezing. 4. When a gas turns to a liquid, the energy of the particles decreases. 5. Vaporization is the reverse of condensing.

More Information
These changes are physical processes involving energy changes but not chemical changes. Understanding these terms helps in identifying processes occurring in everyday substances.
Tips
A common mistake is confusing the processes of vaporization and condensation since they involve opposite energy changes.
