Question

State similarities and differences between laboratory thermometer and clinical thermometer.

Answer 1

Hint: Thermometer is a device that is used to measure temperature of a body or an object or an environment.
Clinical thermometer is used to measure the temperature of a living body. More precisely developed for a human body.
Laboratory thermometer is used to measure temperature of things other than human body

Complete step-by-step answer:
The similarities between laboratory thermometer and clinical thermometer are:
1. Both are made of glass and consist of a long narrow tube made up of glass.
2. Both of them have a bulb at one end.
3. Both the meters give readings with the mercury that is inside the thermometer.
4. Celsius scale is present in both the thermometer.

Points of difference	Clinical Thermometer	Laboratory Thermometer
Temperature Range	35-42 degree Celsius.	10-100 degree Celsius.
Uses	To measure human body temperature.	Used to measure temperature in the laboratory.
Kink	It has a kink which prevents immediate backflow of mercury.	It does not have a kink.

Additional Information:
The first medical thermometer was invented by Sir Thomas Albut in 1867. It was six inches long and took about five minutes to take a person's temperature.

Note:
i. One should never use a clinical thermometer in the laboratory vice versa.
ii. Mercury is the only substance other than glass that is used in thermometers.
iii. Both of them exhibit Celsius scale.
