Chapter 11.8, Problem 1PPC

Interpretation Introduction

Interpretation:

The phase diagram showing given changes in temperature, pressure, and phase is to be identified.

Concept introduction:

A phase diagram is a graph that represents the solid, liquid, and gaseous phases of a substance at different pressures and temperatures.

The x-axis represents temperature change and y-axis represents pressure change.

The lines are the boundary between two phases and represent the conditions under which the two phases are in equilibrium.

Moving from left to right horizontally represents temperature increase and moving from right to left horizontally represents temperature decrease at constant pressure.

Moving downward vertically represents pressure decrease and moving upward vertically represents pressure increase at constant temperatures.
