Hint: Thermometer derived from two words (thermos which means hot; metron which means measure) is the universal instrument used to measure temperature.
Temperature is the measurable degree of hotness or coldness. Temperature is a mathematical representation of heat. There are different units used to measure temperatures, like Celsius, Kelvin \[\left( K \right)\], and Fahrenheit.
Some sets of thermometers that are used to measure the temperature of the body while another set of thermometers to measure boiling point and freezing point during experiments.
Complete step-by-step answer:
Properties of thermometric liquid:
The liquid used should be visible to the observer.
There should be a uniform thermal expansion of the liquid.
Types of Thermometer:
Clinical thermometer is also known as the medical thermometer
Laboratory thermometer
Digital thermometer
Infrared ear thermometer
Mercury thermometer
Alcohol in glass thermometer
Constant pressure gas thermometer
Constant volume thermometer
Platinum resistance thermometer
Thermocouple thermometer
Pyrometer thermometer
Clinical Thermometer:
A clinical thermometer is meant for clinical purposes. It is developed for measuring the human body heat. It is designed as a long narrow glass tube with a bulb containing mercury at the end. The normal human body temperature is; that can fluctuate between the ranges to. The level of mercury tells our body heat in. Since mercury is a toxic element in nature, thus these thermometers have been replaced by digital thermometers nowadays.
Range of clinical thermometers is \[{35^ \circ }\] to \[{43^ \circ }\].
Hence the correct option is \[\left( A \right)\]
Note: Clinical thermometers must be sterilized before use for the safe and hygienic check-up.
At normal temperature, the thermometer is washed with water.
Before using it is given a few jerks. We can notice that the jerks bring the level of mercury down.
The thermometer is kept under the tongue or under the arms in order to get the reading on the thermometer.
The thermometer is then held close to the eye in order to see the correct reading.
The temperature difference indicated between the two bigger marks in the thermometer. For e.g. the bigger mark reads \[10\] and the number of divisions is \[5\], then each division reads the value equal to \[\dfrac{{10}}{5} = {\text{ }}2\]
