When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14= C where C is a constant. Suppose that at a certain instant the volume is 440 cubic centimeters and the pressure is 79 kPa and is decreasing at a rate of 14 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm min (Pa stands for Pascal -- it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals.)
