Q. A flask containing air is heated from 300 K to 500 K. The percentage of air escaped to the atmosphere is nearly
A) 40%
B) 30%
C) 80%
D) 60%
Explanation
(d)
$\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$
$\frac{V_{1}}{300} = \frac{V_{2}}{500},\ V_{2} = 1.66\ V$
Volume escape$= \ 1.66\ V - V = 0.66\ V$
$= 66\%$
