1.3 Exercise 11

Avg difficulty 2.5

What is the change in length of a 3.00-cm-long column of mercury if its temperature changes from 37.0°C37.0 ° \text{C} to 40.0°C40.0 ° \text{C}, assuming the mercury is constrained to a cylinder but unconstrained in length? Your answer will show why thermometers contain bulbs at the bottom instead of simple columns of liquid.
