Why does a clinical thermometer have a kink?
The kink in a clinical thermometer prevents the mercury from falling back down when the thermometer is removed from the body. It ensures that the highest temperature reached is recorded until it is reset.
What is the mercury called on a clinical thermometer?
The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.

Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
Why does a clinical thermometer has a kink in its tube?
So the working fluid doesn't flow back into the bulb when the it is removed from the heat source. This makes a clinical thermometer "sticky"; it retains the reading of the highest temperature experienced until it is "reset" by shaking.

How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink in a mercury or alcohol clinical thermometer helps to prevent the mercury or alcohol from flowing back into the bulb once the thermometer is removed from a patient's body. This ensures that the maximum temperature reached during measurement is retained for reading.
What are some advantages of a clinical thermometer?
The kink at one end of the thermometer will helps us to read the temperature frequently. P. bhanusree Jhonson grammar school, hyd

Why do lab thermometer not have a kink?
Lab thermometers do not have a kink in the tube because it allows for a continuous and smooth flow of the liquid inside the thermometer, ensuring accurate readings. A kink could create air bubbles or blockages that would affect the movement of the liquid and compromise the thermometer's precision.
Why there is kink in clinical thermometer?
In a normal clinical thermometer, the mercury moves up and down the capillary tube as the temperature changes and thus if you removed it from contact with the patient the reading would steadily fall as it cooed. As you need a clinical thermometer to give you a reading of the patients temperature even after it has been removed from the patient, you need to stop the mercury shrinking back into the reservoir. The 'kink' breaks the connection between the mercury in the capillary tube and the reservoir so the reading given is accurate. On the other hand before it can be used again the mercury in the capillary tube has to be vigorously shaken back into the reservoir.On a point of interest, clinical thermometers are getting very rare because they have been phased out due to concerns regarding mercury poisoning should they break in use.
