Q. $400 \,cm^{3}$ of oxygen at $27^{\circ}C$ were cooled to -$3^{\circ}C$ without change in pressure. The contraction in volume will be

A
$40 \,cm^{3}$

B
$30\, cm^{3}$
8%
C
$44.4 \,cm^{3}$
23%
D
$360\, cm^{3}$
15%
Solution:
$V_{2}=\frac{T_{2}}{T_{1}} $
$\Rightarrow V_{2}=\frac{270\,K}{300\,K}.400\,cm^{3}=360\,cm^{3}$
Contraction $V_{1}-V_{2}=400-360=40\,cm^{3}$
