Question

A phase diagram is a pressure-temperature graph that shows the ranges of temperature and pressure over which each phase is stable. The phase diagram is divided into three regions, each region representing one stable phase: solid, liquid, or gas. There are three boundary lines that separate the phases from one another. These boundary lines represent the equilibrium between two phases. The point at which the three boundary lines intersect is called the triple point. All three phases can exist in equilibrium with each other at this point. Select the image or click here to explore the interactive activity that shows the phase diagram for CO2 . Using the interactive diagram, you can observe what the phase of CO2 is at a particular temperature and pressure by moving the cursor to that point on the phase diagram. The animation also shows the type of movement experienced by CO2 molecules in a particular phase. The general form of a phase diagram is given below. Observe that this phase diagram is divided into three regions by the blue boundary lines similar to the way the interactive phase diagram for CO2 was divided. Compare this general form of this phase diagram with the interactive phase diagram for CO2 and classify points a through g on the phase diagram according to the number of phases present at each point. Drag the appropriate points to their respective bins.

Explanation / Answer

a,b,c-one phase d,e,f-two phases g- three phases
