A mercury thermometer is constructed as shown above. The glass capillary tube has a diameter of 0.004cm, and the bulb has a diameter of 0.24cm. Find the change in height of the mercury column that occurs with a temperature change of 30^oC. State your answer to the nearest mm.

Assume that the dimensions of the capillary tube will not change (so assume that only the bulb experiences temperature change!)

The linear expansion coefficient of glass is 3.1x10^-6 (^oC)^-1

The volume expansion coefficient of mercury is 182x10^-6 (^oC)^-1
