Question

Convert 100 K into Fahrenheit scale.

• A. ${60.6}^{\circ }F$
• B. ${70.6}^{\circ }F$
• C. ${90.6}^{\circ }F$
• D. ${80.6}^{\circ }F$

Answer 1

The correct option is D ${80.6}^{\circ }F$

Given, temperature in Kelvin scale,$K=300K$
Let $F$ be the temperature in Fahrenheit scale and $C$ be the temperature in Celsius scale.
We know, $K=273+C$ $\Rightarrow C=300-273={27}^{\circ }C$
The relation connecting $C$ and $F$ is :
$C=\frac{5}{9}(F-32)$
$\Rightarrow 27=\frac{5}{9}(F-32)$
$\Rightarrow F=\left(\frac{27\times 9}{5}\right)+32={80.6}^{\circ }F$
