Question

The boiling points of Diethyl ether, Acetone and n-Butyl alcohol are ${35}^{\circ }C,{56}^{\circ }C$ and ${118}^{\circ }C$ respectively. Which one of the following correctly represents their boiling points in Kelvin scale?

• A. 306 K, 329 K, 391 K
• B. 308 K, 329 K, 391 K
• C. 308 K, 329 K, 392 K
• D. 329 K, 392 K, 308 K

Answer 1

The correct option is B 308 K, 329 K, 391 K

$T\left(K\right)=273+t^{\circ }C$
Hence (35+273), (56 + 273) and (118 + 273) respectively i.e., 308 K, 329 K and 391 K.
