Question

Range of clinical thermometer in Kelvin scale is:

• A. 310 K to 355 K
• B. 308 K to 315 K
• C. 208 K to 350 K
• D. 308 K to 425 K

Answer 1

The correct option is B 308 K to 315 K

The range of clinical thermometer in Celsius scale is ${35}^{\circ }C$ to ${42}^{\circ }C$.
If K is the temperature in Kelvin scale and C is the temperature in degree Celsius, then, K = 273 + C.
Therefore, the range of clinical thermometer in Kelvin scale is ($273+35$) to ($273+42$)
I.e, $308K$ and $315K$
