Question

8. The boiling points of diethyl ether, acetone and n-butyl alcohol are 35°C, 56°C and
118°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

Hey MATE!!!

To convert degree celcius to Kelvin we add 273 to the given temperature.

$\huge\boxed{<strong><u><em>T°</em><em>C </em></u></strong><strong><em><u>\</u></em></strong><strong><em><u>:</u></em></strong><strong><u><em>=</em><em> </em></u></strong><strong><em><u>\</u></em></strong><strong><em><u>:</u></em></strong><strong><u><em>(</em><em>T </em><em>+</em><em>2</em><em>7</em><em>3</em><em>)</em><em>K</em></u></strong>}<strong><em><u> </u></em></strong>$

Now we convert the values in the given question :

1) 35°C => 35 + 273 => 308 K

2) 56°C => 56 + 273 => 329 K

3) 118°C => 118 + 273 => 391 K

Hence, option (C) is the correct answer to the given question.

Hope it helps

HAKUNA MATATA :))

Answer 2

Answer:

(c) The correct order of boiling points of diethyl ether, acetone and n-butyl alcohol in kelvin scale is

308 K, 329 K and 391 K, which can be explained as (v T°C + 273 = 7K).

Boiling point of diethyl ether = 35°C + 273 = 308 K

Boiling point of acetone = 56°C + 273 = 329 K

Boiling point of n-butyl alcohol = 118°C + 273 = 391 K
