document.write( "Question 673759: The volume of gas varies directly as its temperature and inversely as its pressure. At a temperature of 100 kelvin and a pressure of 15 kilograms per square meter, the gas occupies a volume of 20 cubic meters. Find the volume at a temperature of 150 kelvin and a pressure of 20 kilograms per square meter. \n" ); document.write( "

\"volume+=+k+%2A%28temperature%2FPressure%29\"
\n" ); document.write( "Plug in the value given as the first part of the problem.
\n" ); document.write( "Then solve to find k
\n" ); document.write( "\"20+=+k+%2A%28100%2F15%29+\"
\n" ); document.write( "\"20+%2A+15%2F100+=+k\"
\n" ); document.write( "\"3+=+k\"\r
\n" ); document.write( "\n" ); document.write( "so
\n" ); document.write( "\"volume+=+3+%2A+%28temperature%2Fpressure%29\"
\n" ); document.write( "Use that to solve for the second volume
\n" ); document.write( "\"volume+=+3+%2A+%28150%2F20%29\"
\n" ); document.write( "\"volume+=+22.5\" cubic meters\r
\n" ); document.write( "\n" ); document.write( "
