Keeping the temperature as constant, a gas is compressed four times of its initial pressure. The volume of gas in the container changing from 20cc (V_(1)" cc") to V_(2) cc. find the final volume V_(2).

<P>

Solution :Initial pressure `(P_(1))=P`
FINA pressure `(P_(2))=4P`
Initial volume`(V_(1))=2ee =320 cm^(2)`
Final volume `(V_(2))=?`
Using Boyle.s Law,PV= constant
`P_(1)V_(1)=P_(2)V_(2)`
`V_(2)=(P_(1))/(P_(2))xxV_(1)=(P)/(4P)xx20 cm^(3)`
`V_(2)=5 cm^(3)`
