When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV1.4=C where C is a constant. Suppose that at a certain instant the volume is 320 cm3, and the pressure is 95 kPa (kPa = kiloPascals) and is decreasing at a rate of 11 kPa/minute. At what rate is the volume increasing at this instant?
