The kink present in the clinical thermometer prevents the mercury from falling or rising when taken out of the mouth.

The mercury does not fall or rise in a clinical thermometer when taken out of the mouth because of the presence of kink. It prevents mercury level from falling on its own.

Shreya Pandey 5 years, 5 months ago

In clinical thermometers, there is a small bent at the bottom of the tube containing mercury. It is called a kink. The kink prevents the mercury level from falling down on its own. Due to this, the temperature does not decrease immediately after removing the thermometer from the mouth.
