Question

A gas at 240 K is heated to ${127}^{\circ }C$. Find the percentage change in the volume of the gas (pressure remaining constant).

Answer 1

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

$V_1=V,T_1=240K,T_2=273+127=400K$

$V_2=\frac{V\times 400}{240}=1.666V$

%Change in volume$=(1.666V-V)\times 100=66.6$%
