Question

The normal temperature of the human body is $37^\circ C$. What will be its value on the a) Fahrenheit scale, b) Kelvin scale?

Answer 1

Hint: The average temperature range found in humans is referred to as normal human body temperature (normothermia, euthermia). The average human body temperature range is \[36.5^\circ -37^\circ C\](\[97.7^\circ -98.6^\circ F\]). The temperature measurements are Celsius, Fahrenheit, and Kelvin. A formula has to be used that can convert the values of temperature from one unit to another.

Formula used:
$\dfrac{C}{5} = \dfrac{{F - 32}}{9}$
${T_K} = {T_C} + 273$

Complete step by step answer:
Heat transfers from the higher temperature body to the lower temperature body when the temperature difference is maintained. The amount of heat transferred is determined by several parameters, including the temperature differential, material qualities, and the amount of substance. A thermometer is used to determine the temperature. On heating, liquids generally expand after transmitting heat. It is the sole functioning principle of thermometers.
If the temperature measured in Celsius, the Fahrenheit value is
\[\dfrac{C}{5} = \dfrac{{F - 32}}{9}\]
Given temperature is \[37^\circ C\]. As a result, the Fahrenheit temperature will be
\[\dfrac{C}{5} = \dfrac{{F - 32}}{9}\]
\[ \Rightarrow \dfrac{{37}}{5} = \dfrac{{F - 32}}{9}\]
$ \Rightarrow F = \dfrac{{9 \times 37}}{5} + 32$
$ \Rightarrow F = 66.6 + 32$
$ \Rightarrow F = 98.6^\circ F$
So, the temperature is $98.6^\circ F$
In kelvin scale the formula,
${T_K} = {T_C} + 273$
${T_K}$ - Temperature in kelvin.
${T_C}$ - Temperature in Celsius.
${T_K} = {T_C} + 273$
$ \Rightarrow {T_K} = 37 + 273$
$ \Rightarrow {T_K} = 310K$
Therefore, on the Kelvin scale, the temperature will be \[310\] kelvin.

Note: When the thermometer comes into contact with the human body, the mercury-filled bulb inside heats up. The heat will pass through the mercury. When mercury is heated, it expands in the thermometer, and the calibrated readings on the thermometer give us the human body's temperature.
Rather than utilizing water as a thermometer liquid, we usually use mercury because mercury has a higher coefficient of thermal expansion than water, allowing us to acquire more accurate readings even at low temperatures.
Everyone has a specific body temperature. Gender, age, time of day, amount of effort, health status (such as disease and menstruation), part of the body measured, level of awareness (awake, sleeping, sedated), and emotions all play a role. The body can be measured using a variety of devices.
