Problem: Mercury is often used as an expansion medium in a thermometer. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises. Suppose a mercury thermometer contains 3.400 g of mercury and has a capillary that is 0.210 mm in diameter.How far does the mercury rise in the capillary when the temperature changes from 0.0 oC to 25.0 oC? The density of mercury at these temperatures is 13.596 g/cm3 and 13.534 g/cm3, respectively.

In this problem, we are asked to determine how far does the mercury rise in the capillary when the temperature changes from 0.0 oC to 25.0 oC.


To solve this problem, we need to:

Step 1. Determine the volume of mercury at different temperatures.
Step 2. Calculate the cross-section area of the mercury in the capillary tube.
Step 3. Determine the height of the mercury rose in the capillary.
