Question

The normal boiling and freezing points of argon are 87.3 K and 84.0 K. The triple point is at 82.7 K and 0.68 atmosphere. Use the data above to draw a phase diagram for argon. In the diagram, label the spots where the solid, liquid, and gas phases are stable as well as show the position of the normal boiling point.

Answer 1

INFORMATION:

We know that:

- The normal boiling and freezing points of argon are 87.3 K and 84.0 K

- The triple point is at 82.7 K and 0.68 atmosphere.

And we must draw a phase diagram for argon using the data

STEP BY STEP EXPLANATION:

To draw the diagram, we must graph first the triple point since it is the common point for the three states of the argon

Then, we need to use that the normal boiling and freezing points of argon are 87.3 K and 84.0 K to divide he states of the argon in the graph

Finally, we need to show the position of the normal boiling point

So, we obtain the next graph
