Question

What temperature is ${75}^{o}F$ on the kelvin scale ?

• A. 24 K
• B. 348 K
• C. 297 K
• D. 215 K

Answer 1

Answer: (C)

297 K

Relationship between Fahrenheit and Kelvin scale

$\frac{F-32}{180}=\frac{K-273}{100}$

As $F={75}^{o}F$

$⟹\left(\frac{75-32}{180}\right)\left(100\right)=K-273$

$⟹\frac{430}{18}+273=K$

${75}^{o}F$ in Kelvin scale $=297K$

Hence, the correct option is $\text{C}$
