1.	At constant temperature a gas occupies a volume of 200 mL at a pressure of 0.720 bar. It is subjected to an external pressure of 0.900 bar. What is the resulting volume ?
Answer» <P> SOLUTION :GIVEN `V_(1)=200mL` `P_(1)=0.720mL` `P_(2)=0.900`bar `V_(2)=?` `V_(1)P_(1)=P_(2)V_(2)` `thereforeV_(2)=(P_(1)V_(1))/(P_(2))=(0.720xx200)/(0.900)=160mL`
