Question 1104871
-------------------------------------------------------------------------------
the pressure (P) of a gas is inversely proportional to the volume(V) of a gas.
-------------------------------------------------------------------------------


{{{P=k/V}}}



--------------------------------------------------------
pressure of a gas is o.75 kg/cm^2 when the volume is 8000 cm^3.
--------------------------------------------------------


{{{k=PV}}}

{{{k=0.75*8000}}}

{{{k=6000}}}



REVISE 

{{{P=6000/V}}}
