1.	A gas occupies a volume of 12 litre under a pressure of 75 cm of Hg. What volume does it occupy under the same temperature when the pressure becomes 72 cm of Hg?
Answer» Solution :`P_(1)=75cm` of G Hg , `V_(1)=12` litres , `P_(2)=72` cm of Hg , `V_(2)=?` From Boyle.s LAW, `P_(1)V_(1)=P_(2)V_(2)RARR V_(2)=(P_(1)V_(1))/P_(2)=(75 times 12)/72=12.5` litres.
