State similarities and differences between the laboratory thermometer and the clinical thermometer

Answer: Both are used to measure temperature accurately. However, a clinical thermometer measures body temperature within the range of 35°C to 42°C, while a laboratory thermometer covers a broader range, typically from -10°C to 110°C. Clinical thermometers have a constriction to prevent mercury backflow, while laboratory thermometers do not, ensuring continuous temperature reading.

Complete Answer:

Here are the similarities and differences between Laboratory Thermometer and Clinical Thermometer

Similarities:

1. The laboratory thermometer and the clinical thermometer are both used to measure temperature.
2. Both contain mercury or alcohol that expands when heated.
3. Both have a long glass tube with a scale marked in degrees Celsius.

Difference: 

Clinical thermometer	Laboratory thermometer
A clinical thermometer is used to measure the human body temperature	The aim of a laboratory thermometer is not to measure body temperature; rather, it is typically used to measure items whose temperature ranges are outside of those of the average human body.
Clinical thermometers have a temperature range of 35°C to 42°C	Laboratory thermometers have a wider range, like –10°C to 110°C
Clinical thermometers have a kink (a small bend) in the tube to prevent mercury from falling back quickly.	Laboratory thermometers do not have this kink

Conclusion: A thermometer is a device that measures temperature because the word thermo means temperature, and metros implies measurement.
