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.
Labeled diagram of a clinical thermometer?
Well I have being trying for some time and yet still cant draw it. My only option was to go on Google .
What is the working and construction of thermometer?
WORKING: Place the bulb of the thermometer filled with mercury in a vessel ov small pieces of ice the mercury will arise in the tube and will come to rest at a certain point.this point shows the melting point of ice. CONSTRUCTION:A thermometer consists of a glass bulb filled with mercury.A cappilary tube arises from this bulb.Due to the narrow bore of the tube a small change in the volume of the mercury becomes significiantly visible.
Why is mercury in a thermometer stored in a narrow tube?
Like most materials, mercury expands when heated. By storing the mercury in a narrow tube, as the mercury gets warmer (and therefore expands) it will rise up the tube, allowing the temperature to be determined based on how high up the tube the mercury has risen.

How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.
What does a clinical thermometer consist of?
a clinical thermometer consists of mercury(Hg) concealed inside a glass tube with a bulb at the bottom. the bulb portion has the mercury and is thermo-sensitive. owing to the rise in temperature, when kept under the tongue of a patient, the mercury rises over the calibrated tube portion.
