6. Draw a labelled diagram of a clinical
thermometer. Explain the function of the
kink in the stem.
Answers
Explanation:
Kink in the Mercury thermometer helps to prevents the falling of mercury present in capillary tube into bulb. It ensures that the user takes the correct reading of temperature.
That's the reason a person before taking a new reading must give a sudden shake to the clinical thermometer so that the mercury level comes to normal .
Hence Kink in mercury thermometer plays a important role without which appropriate reading of temperature is not possible.
Explain the function of the
kink in the stem.
Explanation:
The kink is designed to 'break' the thread of the mercury (or alcohol), so the part closest to the bulb contracts back into the bulb, while the remaining section of mercury just contracts where it is in the tube. ... Without the kink, more liquid would contract back to the bulb, leading to consistently low readings.
