What is the function of ‘kink' in a clinical thermometer?​

Answer 1

Answer:

Kink in the clinical thermometer helps to prohibit the falling of mercury present in the capillary tube into the bulb ensuring that a person should get the correct reading even after taking the thermometer out from his/her mouth.
