Question

Temperature of a body is ${125}^{\circ }C$. Calculate the temperature in Fahrenheit and Kelvin scale.

• A. ${467}^{\circ }F$ and $289K$
• B. ${287}^{\circ }F$ and $369K$
• C. ${367}^{\circ }F$ and $429K$
• D. ${257}^{\circ }F$ and $398K$

Answer 1

The correct option is D ${257}^{\circ }F$ and $398K$

Given, temperature in Celsius scale, $C={125}^{\circ }C$.
Let $F$ be the temperature in Fahrenheit scale and $K$ be the temperature in Kelvin scale.
We know that, $C=\frac{5}{9}(F-32)$
$\Rightarrow 125=\frac{5}{9}(F-32)$
$\Rightarrow F=(\frac{9}{5}\times 125)+32={257}^{\circ }F$

Also we know that, $K=273+C$
$\Rightarrow K=273+125=398K$
