PHASE DIAGRAM

A phase diagram is a graphical way to summarize the conditions under which equilibria exist between the
different states of matter. It also allows us to predict the phase of a substance that is stable at any given
temperature and pressure.
Critical Thinking Questions
1. What Label is on the x-axis?
2. What Label is on the y-axis?
3. List the three phases of matter that are on the diagram.
4. At which point do all three phases on the diagram meet?
5. In your own words, define what you think the triple point is.
6. The line extending from the triple point to the critical point stops. What does this mean in terms of
phase change?
7. In your own words, define what you think the critical point is.
