PRACTICAL PYROMETRY
CHAPTER I STANDARD TEMPERATURE SCALES
1. The Comparison of Temperatures. - Lengths can be directly measured by means of a foot rule, a meter bar, a surveyor's chain or other standard of length. Similarly, volumes can be measured in terms of some standard of volume such as a gallon, bushel, or cubic foot. Temperatures, however, cannot be directly measured. In fact, temperatures can be compared only indirectly in terms of some property which changes in magnitude when temperature changes. For example, since when under constant pressure the length and volume of most substances increase as their temperature increases, changes of length and volume can be used for the comparison of temperatures.
Again, since the pressure of a fixed mass of gas kept at constant volume increases when the temperature of the gas is raised, changes in the pressure of a gas under these conditions can be used as a measure of the changes of temperature.
