A mercury thermometer has a cylindrical capillary tube with an internal diameter of 0.2 mm. If the volume of the thermometer and that of the bulb are not affected by temperature, what volume must the bulb have if a sensitivity of 2mm/ degree C is to be obtained?
Assume operating near 24 C
Assume that the stem volume is negligible compared with the bulb internal volume.
Differential expansion coefficient of Hg=1.82*10-4mL/(mL*C)
I just need a general explanation of it please- Thanks!
