Question

a sample of gas occupies volume of 2.74 DM cube at 0.9 bar and 27 degree Celsius what will be the volume at 0.75 bar and 15 degree celsius​

Answer 1

${\mathfrak{\purple{\underline{\underline{Answer:-}}}}}$

$\sf{V_{2}=0.122\;dm^{3}}$

${\mathfrak{\purple{\underline{\underline{Explanation:-}}}}}$

Given:-

$\sf{V_{1}=2.74\;dm^{3}}$

$\sf{P_{1}=0.9\;bar}$

$\sf{T_{1}=27^{\circ}C}$

$\sf{V_{2}=?}$

$\sf{P_{2}=0.75\;bar}$

$\sf{T_{2}=15^{\circ}C}$

$\sf{Substituting\;values\;in\;the\;equation,}$

$\sf{\dfrac{P_{1}V_{1}}{T_{1}}=\dfrac{P_{2}V_{2}}{T_{2}}}$

$\sf{We\;get:}$

$\sf{\dfrac{0.9.(2.74)}{27} =\dfrac{1.75V_{2}}{15}}$

$\large{\sf{V_{2}=0.122\;dm^{3}}}$
