Question

-40${}^o$F on absolute scale is equal to

• A. 0 K
• B. 233 K
• C. 273 K
• D. 313 K

Answer 1

The correct option is B 233 K

he temperature T in Kelvin (K) is equal to the temperature T in degrees Fahrenheit (°F) plus 459.67, times 5/9:

$T\left(K\right)=\left(T\right(°F)+459.67)\times 5/9$

Put T(°F) =$-{40}^{0}F$

$T\left(K\right)=(-40+459.67)\times 5/9$

T(K) =$233K$
