When atmospheric pressure decreases to 60 mm of Hg, liquid boils below the boiling temperature. According to the graph, CCl 4 boils at 349 K, when atmospheric pressure approaches 760 mm of Hg. At 60 mm of Hg , CCl 4 boils at temperature ≈ 281 K.

Q. The figure given below shows the variation of vapour pressure of different liquids with temperature.

At high altitude, atmospheric pressure is low (say $60 mm H g$ ). At what temperature does liquid $CC l_{4}$ boils?

$273 K$

$281 K$

$349 K$

$373 K$

When atmospheric pressure decreases to $60 mm$ of $H g$ , liquid boils below the boiling temperature.
According to the graph, $CC l_{4}$ boils at $349 K$ , when atmospheric pressure approaches $760 mm$ of $H g$ .
At $60 mm$ of $H g, CC l_{4}$ boils at temperature $\approx 281 K$ .
