Question

a 2.0 liter container of nitrogen has a pressure at 3.2 atm. what volume would be necessary to decrease the pressure to 1.0 atm

Answer 1

Pressure of Nitrogen gas having volume 2.0 L is 3.2 atm

$P_1= 3.2 atm$ ,$V_1= 2.0 L$

Now, pressure reduced to 1 atm at constant temp

so,

$P_1V_1= P_2V_2$

$3.2\times 2= 1 \times V_2$

$V_2 = 6.3 L$

So, volume of gas become 6.4 L
