1. What are the four states of matter?

2. What terms do we use to name the phase changes, such as liquid to gas, gas to solid, gas to liquid, solid to gas, etc.?

3. Some people say "To change the states of matter, heat transfer must happen." Do you agree or disagree? Explain with examples.

4. What is entropy? How does the entropy of the system change along with the phase change from solid to liquid, and liquid to gas?
