Question

At ______ atm of pressure the volume of a gas at $5$ atm will be doubled at constant temperature.

Answer 1

Final pressure $P_2$=?

Initial pressure $P_1$= $5$ atm

Final volume $V_2=2V_1$

$P_1{V}_1=P_2{V}_2⟹P_2$

$=\frac{5atm\times V_1}{{2V}_1}$

$=2.5atm$

$\therefore$ At $2.5$ atm of pressure the volume of the gas at $5$ atm will be doubled at constant temperature.
