Question 8
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, 392 K
(c) 308 K, 329 K, 391 K
(d) 329 K, 392 K, 308 K

Answer 1

The boiling points of diethyl ether, acetone and n-butyl alcohol are 35${}^{\circ }$C, 56${}^{\circ }$C and 118${}^{\circ }$C.
The temperature is converted from celcius to kelvin using the relation:
K = 273 + ${}^{\circ }$C
308 K = 273 + 35${}^{\circ }$C
329 K= 273 + 56${}^{\circ }$C
391 K = 273 + 118${}^{\circ }$C
Hence option (c) is correct.
