Question

State similarities and difference between the laboratory thermometer and the clinical thermometer.

Answer 1

Similarities between Laboratory and Clinical thermometers

1. Both thermometers consist of long narrow uniform glass tubes.
2. Both have a bulb at one end.
3. Both contain mercury in the bulb.
4. Both use the Celsius scale on a glass tube.

Difference between Laboratory and Clinical thermometers

Clinical thermometer	Laboratory thermometer
A clinical thermometer reads temperature ${35}^{°}\mathrm{C}$ to ${45}^{°}\mathrm{C}$.	A laboratory thermometer ranges from $-{10}^{°}\mathrm{C}$ to 110${110}^{°}\mathrm{C}$.
The clinical thermometer has a kink near the bulb.	There is no kink in the laboratory thermometer.
Due to kink mercury does not fall down on its own in clinical thermometers.	Mercury should fall on its own in a laboratory thermometer.

Therefore, above are the similarities and differences between clinical and laboratory thermometers.
