Keeping the temperature as constant, a gas is compressed 4 times of its initial pressure. The volume of gas in the container changing from 20 $cc$ (

$V_{1}$ cc) to

$V_{2}$ cc.

Find the final volume

$V_{2}$ .

Let us consider,

Initial Pressure (

$P_{1}$ )

$=$

$P$

Final Pressure (

$P_{2}$ )

$=$ 4

$P$ (Since, the final pressure is 4 times of its initial pressure)

Initial Volume (

$V_{1}$ )

$=$ 20

$cc$ (=\) 20

${cm}^{3}$

From the data,

is used to solve the problem.

$\frac{P}{V}\ =\ Constant$
$P \times V\ =\ Constant$
$P \times V \times T\ =\ Constant$

Substitute the values,

Final volume of the gas

$=$

${cm}^{3}$
