b. Because of the slightly nonlinear temperature depen- dence of the specific volume of liquid mercury, there is an inherent error in using a mercury-filled ther- mometer that has been calibrated against an ideal gas thermometer at only 0°C and 100°C. Using the data in the table, prepare a graph of the error, AT, as a function of temperature. c. Why does a common mercury thermometer consist of a large-volume mercury-filled bulb attached to a capillary tube?
