Chapter 11, Problem 97QP

Interpretation Introduction

Interpretation:

The phase changes in water on changing temperature and pressure is to be predicted.

Concept Introduction:

A phase diagram is a graph that represents the solid, liquid, and gaseous phase 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 downwards vertically represents pressure decrease and moving upwards vertically represents pressure increase at constant temperatures.
