Q
Q: Which of the following statements is true regarding the phase diagram of a substance?
Solution: The triple point on a phase diagram is the unique set of conditions at which all three phases (solid, liquid, gas) coexist in equilibrium.
Steps: 4
Step 1: Understand what a phase diagram is. A phase diagram shows the different states (solid, liquid, gas) of a substance at various temperatures and pressures.
Step 2: Identify the triple point on the phase diagram. The triple point is a specific point where the lines separating the solid, liquid, and gas phases meet.
Step 3: Recognize what happens at the triple point. At this point, all three phases (solid, liquid, and gas) can exist together in balance.
Step 4: Conclude that the statement about the triple point being the unique set of conditions for all three phases to coexist is true.
