Question

The formula $\mathrm{K}=\mathrm{C}+273.15$ converts temperatures from degrees Celsius $C$ to Kelvin $K$. Which of the following formulas is not correct?

• A. $K-C=273.15$
• B. $C=K-273.15$
• C. $C-K=-273.15$
• D. $C=K+273.15$

Answer 1

The correct option is D

$C=K+273.15$

Find the relation between Celsius $C$ to Kelvin $K$.

Given, expressions is $\mathrm{K}=\mathrm{C}+273.15$.

This can be written as

$$\begin{gathered} \Rightarrow K-C=273.15 \\ \Rightarrow C=K-273.15 \\ \Rightarrow C-K=-273.15 \end{gathered}$$

But cannot be written as $C=K+273.15$.

Hence, answer is (D) $C=K+273.15$.
