Question

The normal temperature of the human body on the Kelvin scale is _____ K.
(a) 280
(b) 290
(c) 300
(d) 310

Answer 1

Hint: Kelvin is the absolute-scale unit of temperature measurement. The degree Celsius is a Celsius-scale temperature unit and one degree celsius is equal to -272.15 kelvin. Typically the average body temperature is about 37 degrees celsius.

Complete answer:
The scale of Celsius is a temperature scale based on 0 degree for water freezing point and 100 degree for water boiling point. Its unit is in C. Kelvin is the temperature base unit in the International System of Units (SI) and has the unit symbol K.
The average human body temperature is 36.85 degrees Celsius.
${ T }_{ k }\rightarrow { T }_{ c }+273.5$
${ T }_{ k }\rightarrow 36.8+273.5$
Therefore,
${ T }_{ k }=310K$
${ T }_{ k }$ is the temperature in Kelvin and ${ T }_{ c }$ is the temperature in Celsius.
So, the correct answer is, ‘310’.

Additional Information: The kelvin temperature scale has an absolute zero below which there are no temperatures. Absolute zero is the temperature on the Celsius scale equivalent to a temperature of -273.15. In addition to Fahrenheit and Celsius, Kelvin is one of the three best-known scales used to calculate the temperature.

Note: The average human body temperature is around 1-degree Celsius higher in the rectum and 1-degree Celsius lower in the armpits. Our body temperature may display the lowest in the early morning and the highest in the late afternoon, ranging from little 0.3 degrees celsius to 0.6 degrees celsius. Despite these differences, the average natural human body temperature is known to be 37 degrees celsius.
