When air expands adiabatically (without gaining or losing heat), its
pressure and volume are related by the equation where is a constant.
Suppose that at a certain instant the volume is 380 ,
and the pressure is 89 kPa (kPa = kiloPascals)
and is decreasing at a rate of 8 kPa/minute.
At what rate is the volume increasing at this instant?
The volume is increasing at .
