Question

Centigrade or Celsius scale can be converted into Kelvin scale by which of the following formula?

• A. ${}^{o}C=$ Temperature in Kelvin $+273.15$
• B. ${}^{o}C=$ Temperature in Kelvin $-273.15$
  
• C. ${}^{o}C=$ Temperature in Fahrenheit $+273$
  
• D. ${}^{o}C=$ Temperature in Fahrenheit $-273$

Answer 1

Answer: (B)

${}^{o}C=$ Temperature in Kelvin $-273.15$

Zero on the Celsius scale $\left(0^{0}C\right)$ is now defined as the equivalent to $273.15K$, with a temperature difference of $1{}^{o}C$ equivalent to a difference of $1K$, meaning the unit size in each scale is the same.

$T_c=T_k-273.15$

$T_k=$Temperature in kelvin.

$T_c=$Temperature in celsius.

So, the correct option is $B$
