Question

At 2 atm pressure and $0°C$ temperature volume of a gas of fixed mass is 500 cc. Keeping pressure constant if the temperature has been rised to $273°C$, what will be the volume of the gas?

Answer 1

$\mathrm{From}\mathrm{Charles}\text{'}\mathrm{law},\mathrm{volume}\mathrm{of}\mathrm{gas}\mathrm{at}\theta °C\left(V_2\right)=V_0\left(1+\frac{\theta }{273}\right]\mathrm{Where}\mathrm{Vo}=\mathrm{volume}\mathrm{of}\mathrm{gas}\mathrm{at}0°C=500\mathrm{cc};\mathrm{Final}\mathrm{temperature}\left(0\right)=273°C.\therefore \mathrm{So}\mathrm{the}\mathrm{final}\mathrm{volume}\mathrm{of}\mathrm{the}\mathrm{gas}\mathrm{will}\mathrm{be}500\left(1+\frac{273}{273}\right]\mathrm{cc}=\left(500\times 2\right)\mathrm{cc}=1000\mathrm{cc}\mathrm{or}1\mathrm{lit}.$
