Describe the range, sensitivity, and key features of a clinical thermometer compared to a laboratory thermometer.

a) The range of the thermometer is from $-10^\circ\text{C}$ to $110^\circ\text{C}$.

$$\boxed{\text{Range: } -10^\circ\text{C} \text{ to } 110^\circ\text{C}}$$

b) A more sensitive thermometer shows a larger change in its reading for a smaller change in temperature compared to a less sensitive thermometer. It responds more noticeably to slight temperature variations.

c) One change to make the thermometer more sensitive is to use a thinner capillary bore. Alternatively, using a liquid with a larger coefficient of thermal expansion or a larger bulb volume would also increase sensitivity.

d) A clinical thermometer differs from a laboratory thermometer primarily by having a constriction (or kink) in its capillary tube just above the bulb. This constriction prevents the mercury from falling back into the bulb after it has been removed from the patient, allowing the temperature to be read accurately. Laboratory thermometers do not have this constriction. Additionally, clinical thermometers have a much smaller temperature range (e.g., $35^\circ\text{C}$ to $42^\circ\text{C}$) compared to laboratory thermometers.
