When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV 14 = C, where C is a constant. Suppose that at a certain instant the volume is 300 cm and the pre is 80 kPa and is decreasing at a rate of 10 kPa/min. At what rate is the volume increasing at this instant? (Round your answer to the nearest whole number.) cm/min Enter an integer or decimal number [more..) Question Help: Message instructor
