The volume V of a gas varies inversely as the pressure P on it.
\n" ); document.write( " $\"V=k%2FP\"$ where k is a constant.
\n" ); document.write( "You can find the constant or re-write the equation another way.
\n" ); document.write( " $\"PV=k\"$ where the product of pressure and volume equals the constant.
\n" ); document.write( "And then,
\n" ); document.write( " $\"P%5B1%5DV%5B1%5D=P%5B2%5DV%5B2%5D\"$
\n" ); document.write( "Substituting your values,
\n" ); document.write( " $\"23%2A240=30%2AV%5B2%5D\"$
\n" ); document.write( " $\"V%5B2%5D=23%2A240%2F30\"$
\n" ); document.write( " $\"V%5B2%5D=184\"$
\n" ); document.write( "The volume is then 184 cc.
\n" ); document.write( " \n" ); document.write( "

\n" );
