A mercury thermometer is constructed as
shown. The capillary tube has a diameter
of 0.0044 cm, and the bulb has a diameter of
0.1 cm.Neglecting the expansion of the glass, find
the change in height of the mercury column
for a temperature change of 20 ◦C. The
volume expansion coefficient for mercury is
0.000182 (◦C)−1
.
Answer in units of cm.
