Question

The normal temperature of the human body on the Kelvin scale is
A. 280
B. 290
C. 300
D. 310

Answer 1

Hint: Kelvin scale is the SI unit of temperature.

Complete answer:
The normal temperature of the human body is 37 °C but we need to change the scale from °C into Kelvin (K). The relationship between Celsius and Kelvin is given below:
Celsius = Kelvin – 273.15
It may also be written as:
Kelvin = Celsius + 273.15
So, 37°C = Kelvin – 273.15
      Kelvin = 73 + 273.15
Therefore, Kelvin = 310.15 K

Additional information:
Kelvin scale is named in honor of the physicist William Thomson, the first Lord Kelvin.
Kelvin scale is defined by a specific relationship between the pressure of a gas and the temperature.
Kelvin is an absolute temperature scale below which temperature does not exist.
The absolute zero scales is the temperature corresponding to a temperature of -273. 15° on the Celsius scale.
The name of this scale is simply Kelvin not degree Kelvin and its plural form is Kelvins.
Kelvin is commonly used to measure very low and very high temperatures.

So, the correct answer is 310 K.

Note: The normal body temperature in Fahrenheit is 98.6° F which is equal to 37° C. Fahrenheit can be converted to Kelvin by first changing it to Celsius then adding 273.15.
