V_{1} = V, T_{1} = 300 K, T_{2} = 500 K, V_{2} = ?

At constant pressure

V_{1} T_{2} = V_{2} T_{1}

∴ V_{2} = \frac{P _{1} T _{2}}{T _{1}} = \frac{V \times 500}{300} = \frac{5 V}{3}

∴

Volume of air escaped = final volume - initial volume

= \frac{5 V}{3} - V = \frac{2 V}{3}

∴ %

of air escaped

= \frac{2 V /3}{5 V /3} \times 100 = 40%
