Question

At 0°C temperature and constant pressure volume of a gas of fixed mass is 2 lit. Now keeping pressure constant the temperature has been raised to 546°С. Find out the final volume of the gas?

Answer 1

According to Charles' law,
$V_{\theta }=V_0\left(1+\frac{\theta }{273}\right]\mathrm{Where}{V}_0=\mathrm{volume}\mathrm{of}\mathrm{gas}\mathrm{at}0°C=2\mathrm{lit},\theta =\mathrm{final}\mathrm{temperature}=546°C,V_{\theta }=\mathrm{final}\mathrm{volume}\mathrm{of}\mathrm{the}\mathrm{gas}=?\therefore V_{\theta }=2\left(1+\frac{546}{273}\right]\mathrm{lit}=(2\times 3)\mathrm{lit}=6\mathrm{lit}.$
