Problem

The location that indicates conditions under which all phases can co-exist (point A in the graph below) is called


A) triple point.

B) critical point.

C) phase boundary.

D) phase diagram.

Solution

We’re being asked to determine the name of the part of the phase diagram where all phases can co-exist (point A in the graph below)



Recall that a phase diagram shows the transition of matter between solid, liquid, and gas phases as temperature and pressure changes.


In a phase diagram, the different phases can be identified by their location:
