When air expands adiabatically (without gaining or losing heat), its pressure PP and volume VV are related by the equation PV^1.4=C where C is a constant. Suppose that at a certain instant the volume is 410 cubic centimeters and the pressure is 75kPa and is decreasing at a rate of 7 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm3/min
