Question

Raina and Dheeraj measured their body temperature by different thermometers. Raina found it to be \[37\]- degree Celsius and Dheeraj recorded \[98.6\] - degree Fahrenheit. Why?

Answer 1

Hint: As we all know that a thermometer is a device that measures the temperature of a body. It is the degree of hotness or coldness of a body. The three most common units of measurement for temperature are Kelvin, Celsius and Fahrenheit.

Complete answer:
Let’s first understand about the thermometer. A thermometer is a device that measures the temperature of a body. It is a measure of the extent of hotness and coldness of a body. Basically there are three common units for measuring temperature such as Kelvin, Celsius and Fahrenheit. But the body temperature is measured only in either degree Fahrenheit \[{(^o}F)\] or degree Celsius\[{(^o}C)\]. The standard in most countries is degree Celsius \[{(^o}C)\] whereas in the United States, temperature is often measured in degree Fahrenheit \[{(^o}F)\].
According to the question, it is given that Raina and Dheeraj measured their body temperature by different thermometers. Raina found it to be \[37\]- degree Celsius and Dheeraj recorded \[98.6\]- degree Fahrenheit.
We know that the normal body temperature of a human body is \[{37^o}C\] or \[{98.6^o}F\]. This is an average of normal body temperature. The normal body temperature is an oral temperature measured from the mouth i.e. either \[37\] degree Celsius or \[98.6\] degree Fahrenheit.
Here, both Raina and Dheeraj have normal temperatures but they measured their body temperature by different thermometers. One thermometer shows temperature in degrees Celsius and the other one shows in degrees Fahrenheit.

Note:
The three units of temperature i.e. Kelvin, Celsius and Fahrenheit can be converted into each other. We can convert celsius temperature to fahrenheit measure using the formula \[F=\dfrac{9}{5}C+32\] and celsius to kelvin using the formula \[K=C+273\]
