Question

$-{40}^{\circ }$ on absolute scale is equal to

• A. 0K
• B. 233K
• C. 273K
• D. 313K

Answer 1

The correct option is B 233K

For the temperature in kelvin $T_K$ and the temperature in celcius $T_C$,

$T_K$ = 273 + $T_C$

If, $T_C$ = $-{40}^0$

$T_K$ = 273 - 40

$T_K$ = 233K

Hence; option : B (233K).
