A 50cm³ syringe is of internal diameter 3cm. In air, the frictionless plunger is depressed to its full extent and then withdrawn to the 20cm³ mark. If the syringe nozzle is now sealed, on the basis of plunger displacement calculate an effective spring constant for this air-spring system. Note that the adiabatic bulk modulus of air at standard, temperature and pressure (STP) is 142kPa. A 50cm³ syringe is of internal diameter 3cm.
