Question

298 K is approximately what temperature in degrees Celsius?

• A. ${25}^{o}C$
• B. ${24}^{o}C$
• C. ${29}^{o}C$
• D. ${27}^{o}C$

Answer 1

Answer: (A)

${25}^{o}C$

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

$T_k=T_c+273.15$

$T_k=$Temperature in kelvin.

$T_c=$Temperature in celsius.

$T_c=298-273={25}^{0}C$.Option A is correct.
