State similarities and differences between laboratory thermometer and clinical thermometer.

Hint: Study about the thermometers and the working processes of the thermometer. Learn about the different types of thermometers and the use of them. Then we can easily differentiate between them.

Complete Step-by-Step solution:
Thermometers are instruments which are used to measure the temperature. We mainly have two types of thermometer – one is laboratory thermometer and the other is clinical thermometer.
A thermometer consists of a glass tube with a glass bulb at the bottom. We have mercury inside the thermometer. As the bulb of the thermometer is heated up the mercury inside the thermometer will expand and rise up in the tube and if the thermometer is placed in a cold place the mercury will compress and it again settles down.
The laboratory thermometers are used in the laboratory. They are used to measure the temperature of the laboratory and the objects in it.
The clinical thermometer is used in medical processes. This type of thermometer is used to measure human body temperature.
Now, the similarities between the laboratory and the clinical thermometers are:
1. Both of the thermometers are made of glass.
2. Both the thermometers use mercury as the measuring liquid.
3. Celsius scale is present in both the thermometers.
Now, the differences between these two thermometers are:
1. Clinical thermometers are used to measure human body temperature. Laboratory thermometers are used to measure the temperature of laboratories.
2. The least count for both the thermometers are different.
3. The temperature range for a clinical thermometer is from ${{35}^{0}}C$ to ${{42}^{0}}C$ . For a laboratory thermometer the temperature range is $-{{10}^{0}}C$ to ${{110}^{0}}C$.

Note: Try to understand the meaning of clinical thermometer and the laboratory thermometer. From the name of the thermometers you can get an idea about the similarities and the differences of the two types of thermometers.
