Question

What is the use of kink in the clinical thermometer?

Answer 1

Clinical thermometer

• A clinical thermometer is one that is used to assess the temperature of the body on a daily basis.
• The thermometer has a kink near the tip.

The reason behind having kink

• Kink helps in maintaining the level of mercury in thermometer.
• To prevent the mercury level from dropping when the thermometer is removed from the mouth or another region of the body.
• It would have been impossible to get an accurate reading if the kink had not been present.
• This is because the mercury level would otherwise decline, making it difficult to obtain a reading if the clinical thermometer was used in the mouth or elsewhere.
