Question

At constant temperature the pressure of a gas is inversely proportional to it volume .If certain amount of gas occupies a volume of 30cc and exerts a pressure of 85g/cmsquare then find the decrease in its pressure when the same amount of gas occupies a volume of 75cc

Answer 1

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
