A certain volume of gas found to be at a pressure of 1000mm of hg.when the pressure was decreased by 720mm the gas occupied a volume of 2800m³. Calculate initial volume occupied by the gas if the change was done at constant temperature?

pressure dirctly prposnal 1/volume
p1/p2=v2/v1
p1=1000mm Hg,v1=?
p2=720mm Hg,v2=2800m³
1000/720=v2/v1=2800/v1
v1=2800×720/1000
v1=28×72
v1=2016m³

Ans-pressure is directly proportional to 1/volume.
formula-p1/p2=V2/V1
P1=1000mm Hg, V1=?
P2= 720mm Hg, V2=2800m³.
solution -
1000/720=2800/v1
( cross multiple.)
v1=2800×720/1000
therefore - V1= 2,016m³
