Question

400 cm3 of oxygen at 27°C were cooled to -3°C without change in pressure. The contraction in volume will be (A) 40 cm3 (B) 30 cm3 (C) 44.4 cm3 (D) 360 cm3

V2=(T2/T1) ⇒ V2=(270 K/300 K).400 cm3=360 cm3 Contraction V1-V2=400-360=40 cm3

Q. $400 c m^{3}$ of oxygen at $2 7^{\circ} C$ were cooled to - $3^{\circ} C$ without change in pressure. The contraction in volume will be

$40 c m^{3}$

$30 c m^{3}$

$44.4 c m^{3}$

$360 c m^{3}$

$V_{2} = \frac{T _{2}}{T _{1}}$
$\Rightarrow V_{2} = \frac{270 K}{300 K} .400 c m^{3} = 360 c m^{3}$
Contraction $V_{1} - V_{2} = 400 - 360 = 40 c m^{3}$
