Question

The standard temperature of the human body is
(a) 280 Kelvin
(b) 290 Kelvin
(c) 300 Kelvin
(d) 310 Kelvin

Answer 1

Hint: Kelvin and degree Celsius is a unit of temperature measurement. We know that one-degree Celsius is equal to -273.25 Kelvin. The normal body temperature is equal to 37 degrees Celsius.

Correct answer:
The normal temperature of the human body on the Kelvin scale is 310 K. Kelvin is a temperature scale based on molecular motion. On the Kelvin scale, the boiling point of water is 373 K whereas the freezing point of water is 273 k.
-The celsius is another temperature scale in which the boiling point of water is 100 degrees C and the freezing point of water is 0 degrees C.
- According to the international system of units (SI unit), the unit of celsius is C whereas the unit of Kelvin is K.
-The average temperature of the human body is 36.85 degrees Celsius.
Let Tk stand for temperature in Kelvin and TC stands for temperature in celsius.
${ T }_{ k }={ T }_{ c }+{ 273\cdot 5 }$
${ T }_{ k }={ 36\cdot 8 }+{ 273\cdot 5 }$
Therefore, ${ T }_{ k }={ 310 }{ K }$
-On the Kelvin scale, there is an absolute zero below which there will be no temperatures.
-On the Celsius scale, this absolute zero is equivalent to the temperature of - 273.15. It is considered as Kelvin is the best scale for the calculation of temperature.

So, the correct answer is,'310 Kelvin'.

Note:
- Kelvin is a temperature scale based on molecular motion.
-On the Kelvin scale, there is an absolute zero below which there will be no temperatures.
-In the early morning our body temperature is lowest and is highest in the late afternoon.
-The average human body temperature measures one degree Celsius lower under the armpits.
