The normal temperature of human body on the Kelvin Scale is ______.

Answer: D

The normal body temperature is about 310K.

Normal body temperature is about 37°C. To convert Celsius to kelvin, add 273:

\[ \begin{aligned} T &= 37 + 273 \\ &= 310\ \text{K} \end{aligned} \]

280 K, 290 K and 300 K correspond to about 7°C, 17°C and 27°C, all far below body temperature.

As a check, 37°C is 98.6°F, the familiar Fahrenheit figure for normal body temperature, and both describe the same 310 K.
