Vapor pressures have been used for a long time for temperature measurements or for calibrating thermometers against a physical property, since the saturated vapor pressure of a pure substance above its liquid phase depends only on temperature. The physical basis of vapor-pressure thermometry has already been discussed in Section 2.1 of Chapter 2 (see Fig. 2.1).
