Quote: When the temperature falls, the column of Mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. After reading the value, the thermometer must be reset by repeatedly swinging it sharply to shake the mercury back through the constriction. Unquote.

a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol


Why does a clinical thermometer have a narrow constriction?

The narrow constriction in a clinical thermometer prevents the mercury column from dropping back down once body temperature is measured. This allows for an accurate reading of the highest temperature reached by the body.


Why constriction is made in clinical thermometer?

The constriction in a clinical thermometer allows for expansion and contraction of the liquid inside without separating the column of liquid. This ensures accurate temperature readings by preventing the liquid from breaking and forming air bubbles.


Why is it more important to have constriction in a clinical thermometer than in a laboratory one?

Constriction in a clinical thermometer allows for easier reading of temperature changes, important for quick diagnostics. In a laboratory thermometer, a wider range of temperatures may need to be measured with higher precision, so constriction is less important for quick readings.


What is the purpose of the bent constriction in the clinical thermometer?

The bent constriction in the clinical thermometer allows for the expansion and contraction of mercury or alcohol in response to temperature changes. This design prevents the column of liquid from falling back down too quickly, ensuring an accurate reading can be taken by the healthcare provider.
