Question

The boiling point of diethyl ether, acetone and n-butyl alcohol are 35°C, 56°C and 118°C respectively. Which of the following correctly represents their temperature in kelvin scale?

• A. 306 K, 329 K, 391 K
• B. 308 K, 329 K, 398 K
• C. 308 K, 329 K, 391 K
• D. 329 K, 392 K, 308 K

Answer 1

The correct option is C

308 K, 329 K, 391 K

Explanation for correct option-

Kelvin temperature = temperature in Celsius + 273

• So for diethyl ether 35°C
• Kelvin temperature = 35 + 273

= 308 K

• Acetone, 56°C
• Kelvin temperature = 56 + 273

= 329 K

• n-butyl alcohol, 118°C
• Kelvin temperature = 118 + 273

= 391 K

So the correct option is option C.
