Question

The percentage change in the pressure of a gas at constant temperature is $200\%$ (increases). Calculate the percentage change in the volume of the gas.

Answer 1

$PV=nRT$
$P_1{V}_1=P_2{V}_2$
$P_1\times V_1=3P_1{V}_2$
$V_1=3V_1$
$\frac{V_1}{V_2}=3$

Percentage change in volume will be also 200 %
