Problem
A laboratory needs to design a liquid-in-glass thermometer using an organic liquid X that expands uniformly with temperature.
(i) Explain the physical principle that allows liquid X to serve as a temperature-measuring substance.
(ii) Describe the practical steps required to calibrate the thermometer between the ice point and the steam point at standard atmospheric pressure.
(iii) Discuss how the concept of transitive thermal equilibrium ensures that the thermometer reading represents the temperature of any object brought into contact with its bulb.
