Answers
Explanation:
A clinical thermometer is used to measure the temperature of human body. the normal approximate temperature of a human body is 37° C or 98.6° F but it varies depending on age, activity, time of the day, environmental conditions, etc. It rises or falls under a state of illness. Any rise beyond 40°C or 104°F is a medical emergency and requires immediate treatment.
The capillary tube of a clinical thermometer has a kink or bend that does not allow the mercury to flow back into the bulb before the temperature has been read. The mercury column breaks at the kink when it contracts due to decrease in temperature. It prevents the mercury column from falling beyond this point.
This is the reason why we have to shake the thermometer before taking a new reading.
