For this problem, we're being asked to determine how many critical points are present whenever a phase diagram of a pure substance has two solid phases.
Recall that in most phase diagrams, we can distinguish 3 states separated by the lines. Here's an example
But there are special cases that a substance can exhibit two solid phases, example is sulfur. The phase diagram of sulfur can be seen below
If the phase diagram for a pure substance has two and only two solid phases, how many critical points will it have?
