Temperature the pressure of a gas is inversely proportional to its volume.if certain amount of a gas occupies a volume of 30cc and eexertd a pressure of 85 gram per centimetre square then find the decrease in its pressure when the same amount of gas occupies a volume of 75 cc

P is inversely proportional to vol.
This means
\frac{p1}{p2} = \frac{v2}{v1}
Therefore ATQ
\frac{85}{p2} = \frac{75}{30}
p2=17
decrease in pressure = p1-p2
=85-17
=68
Hope it helps.
