Question
(1 pt) 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 390 cm3, and the pressure is 75 kPa (kPa = kiloPascals) and is decreasing at a rate of 8 kPa/minute. At what rate is the volume increasing at this instant?
