In mercury thermometer, mercury of bulb expands and rises in the tube which has linear scale?

A. 1 F – 48 F
B. 8 F – 68 F
C. 54 F – 98 F
D. 94 F – 108 F


(54 F – 98 F) is the right option for a mercury thermometer with a linear scale. The expansion of mercury in the bulb will cause it to rise in the tube, and the linear scale on the tube will indicate the corresponding temperature readings.
